1990s 3-D platforming games were relatively difficult games, especially for my 3-year-old self. I distinctly remember playing Banjo Kazooie back in 1998. With my young, untrained fingers, it was simply impossible to walk across one of the many absurdly thin bridges spanning a dangerous gap without falling. But at that age my will was indomitable, and through countless hours of training, I became a master at crossing thin bridges. Platforming games became unilaterally easier at that point. I could apply the same skillset to each instance.
Then in 2007 Assassin’s Creed came out. Within the first hour of the game, I ended up in the same thin bridge predicament that I remembered so fondly from my days of playing mid-90s platformers for the Nintendo 64. As I set out across the bridge, I moved very slowly, ensuring that my camera was pointed straight ahead and I maintained exactly the course that I wanted.
Then I messed up. I got distracted and my thumb twitched ever so slightly. I mentally flinched, and awaited my inevitable plunge from the bridge. But that plunge never came. Altair remained perched on the bridge as if nothing happened. I stared in disbelief. I knew that I should have fallen.
But a thought occurred to me at that moment: Altair is an expertly trained assassin, not a bear named Banjo bumbling his way through the world. Why should he ever fall unexpectedly while crossing a thin path? How would he have survived his training and his missions up to this point? Maybe it was not actually possible to jump off the bridge.
I decided to test my theory, and try to jump off the bridge. Needless to say it didn’t work. The game prevented me from jumping off the bridge. But rather than be mad at the game for not placing trust in my ability to handle the mechanical difficulty of crossing the bridge, I was pleased. I was pleased because the game really put me in the shoes of the avatar. Altair is a master assassin, and as such needs to be more skilled than the 12-year-old who was controlling his actions as an avatar. By shaping the input I gave the game, the engine preserved the character of Altair.
Authors have a difficult task in creating a narrative for a game. While the author is in command of a majority of the events in a game, there is a single variable which remains outside of their control: the player. The player’s actions are integral to the narrative of a game, and yet are by nature not within the control of the person who wrote the narrative of a game. But that does not necessarily leave the integrity of a game’s narrative to the whims of the player. In order to maintain a game’s narrative consistency, the believability of a story and the actions of the characters contained within, an author may introduce subtle nudges to the player’s actions. Not all games need to do this, however: some narratives are perfectly well maintained by a non-cooperative or incompetent player. But some narratives cannot afford the level of outside shaping to the narrative brought on by a player left entirely to their own devices.
The example I gave above is instructive because it shows how a game’s controls can be an important force in preserving, or not preserving, the narrative consistency of a game. If Altair had been able to fall, it undermines to a degree our ability as players to believe that he is an expert assassin. If Banjo never fell from ledges, maybe it would be hard to believe that we were playing as a human-like bear. By restricting (or noticeably not restricting) the ways in which the player can control the avatar, an author can maintain the consistency of the narrative being presented to the player.
There are many ways that control schemes can have an impact on the internal narrative consistency of a game. But in this and the following two articles, I would like to describe one particular concept: nudgy controls.
In the interest of defining nudges I would like to start by first defining what a game that lacks any nudges looks like. These are games in which an input X on the part of the player reliably yields an output Y within the game, so long as the physics of the engine allow it. For example, pushing left on the control stick always yields moving left, unless there is a physical wall blocking your path. There is a consistency to how the controls work. This is the example of Banjo who will reliably walk left in all situations when the player presses left, even if that results in him falling to his death.
Nudgy controls often resemble the paradigm described above, in that most of the time, an input of X yields output Y. However, in some cases, instead of input X yielding output Y, instead some other output, Z, is yielded. A nudge is an instance of some player input X that typically yields output Y instead yielding output Z, where Y would potentially undermine narrative coherence and Z preserves narrative consistency. As an example, most of the time when a player pushes left on the control stick, the avatar moves left. However, in some minority of cases the avatar instead moves forward. This is the example of Altair, who is nudged away from jumping off of the path to his death, presumably due to his training as an assassin.
Each individual instance of Y occurring instead of Z does not necessarily preserve narrative consistency. Context determines the effectiveness in this regard. The nudges in Assassin’s Creed help to preserve internal narrative consistency, while the same Y-to-Z conversions in Banjo Kazooie would actually undermine the internal narrative consistency. Thus the same mechanic used in Assassin’s Creed would that could be called a nudge would not be called a nudge in Banjo Kazooie. My definition of a nudge contains only the cases in which the instance of Y occurring instead of Z actually does preserve narrative consistency.
There are several kinds of games which maintain narrative consistency explicitly through lack of nudges. These games include:
- Trial-by-death games.
- Games with intentionally obtuse controls.
- Multiplayer skill tournaments
For the remainder of this article, I’ll go over these three types of games that don’t incorporate many nudges. In a follow-up article (Part II), I’ll discuss two differing models for nudgy controls.
- Trial-by-death games
A game’s mechanics can be described as trial-by-death if a majority of the gameplay consists of players dying at least once before success. There are a few possible reasons for the repeated player death. Through the death they could learn about a mechanic they could not have known without extra-gameworld knowledge before succeeding. In a puzzle game, there might be asymmetric information, such that the player cannot learn the solution to the puzzle without failing once at it. Or the game could just throw innovative, difficult challenges at the player that do not require a player death, but simply often result in it. These games are not simply “hard” in a conventional way; players usually cannot avoid dying entirely simply by learning some basic set of skills and mastering them. Unlike Pac-Man, which always features the same ostensive situation but with an ever-escalating degree of difficulty, a trial-by-death game will constantly change the nature of the challenges along with the difficulty.
In order for trial-by-death games to function properly, the player has to be sure that they can trace the effect of their death to their own actions. That way, given the new information they get from dying, they can change the way they play to not get killed again. This is one crucial reason for trial-by-death games not to have nudges in the controls. As the game designers at “Extra Credits” put it, studios like From Software (which created Dark Souls) make a “covenant with the player.” This covenant is that the game has a consistent ruleset. So the rules will not suddenly change, even in extenuating circumstances. If the player gets killed, they can always trace it back to their own actions, rather than pointing at the game engine and saying “it changed the rules.” The flipside is also true, though: if the player succeeds they can rightly congratulate themselves. But this sort of covenant with the player requires consistency in the controls. And so it precludes nudges. There should never be a moment in which input X could spit out either Y or Z. The player should always be sure of the output (if they’ve learned the game sufficiently). If there were nudges, it would be difficult for the player to diagnose the cause of their death, because they may be unsure about whether their own action or the nudge killed them. The inability to diagnose the problem would then lead to an inability to coherently change behavior for another try.
But the lack of nudges also can preserve narrative consistency in trial-by-death games. Dark Souls is an exemplar in this regard. As an undead in a world of gods and other undead, each task requires many attempts before success. By leaving the controls unhindered by nudges, narrative is preserved, since the player inevitably must try each task multiple times before success. In this way the play experience parallels the avatar’s actions. Within the context of the game world, the avatar dies repeatedly attempting to accomplish his or her goal. The player as well most likely fails and tries again many times before success.
2. Games with Intentionally Obtuse Controls
Dark Souls is not unique in being a game that benefits from a non-nudgy control scheme. There are other narratives for which non-nudgy control schemes contribute to narrative consistency. In Octodad, the player controls an octopus masquerading as a normal 1950s breadwinning human father. Octodad has a control scheme which is intentionally obtuse, in that the controls are unintuitive and difficult, yet faithfully respond to player input. In particular, there is a button that lifts his “leg” (which is actually a tentacle), a control stick to move said leg, another control stick to move his “arm” (again actually a tentacle), and many objects in the game are easy to knock over. The player’s difficulty navigating the obtuse control scheme mimics the experience of an octopus attempting with only minor success imitating the normal motions of a human.
Needless to say, it’s very difficult to do. No nudges are necessary in Octodad because either a change from output Y to output Z would help the player control the octopus better, which is antithetical to the narrative of the game, or the change from Y to Z would further inhibit the player. While initially this may seem like a choice that would further enhance the narrative consistency of Octodad, I’d argue that actually wouldn’t be the case. In order to mirror the experience of the inept octopus, the player should also feel as though their own actions are not very effective by their own nature. If the player feels they are forced to fail, they will not be in the same sort of physical situation struggling with the controller as the octopus has in struggling with his body. The introduction of nudges does nothing to further maintain narrative consistency over leaving the game non-nudgy.
3. Multiplayer Skill Tournaments
There exist a wide variety of games that could potentially be considered multiplayer skill tournament games, and any game that fits the archetype is well suited for a control scheme that lacks nudges. I define this category by its three primary features. First, it is a multiplayer game, meaning that multiple players participate in a game. Second, it is a competition of skill, meaning that within the narrative of the game, the most skilled competitor comes out victorious, leaving nothing to chance or sabotage by another player. Third, it takes place in a tournament environment, in which the central narrative thrust is the competition itself, rather than a narrative that contains within it a competition.
A multiplayer skill tournament game doesn’t use nudges because an inclusion of nudges would undermine the narrative of the game. A nudge may cause an of imbalance in the skill levels of the competitors who are controlled by players. This imbalance potentially makes a player question the validity of the victor of the tournament, and thus the narrative itself. One will note that in the absence of any one of the three conditions—that the game is multiplayer, that the game is skill-based, and that the game is a tournament—the requirement for nudge-less gameplay vanishes. A game that is not multiplayer could include non-player characters that are simply more or less skilled than the player. A game that is not skill-based (for instance a game based on randomness) does not require an even playing field. And if the narrative is not a tournament or simply contains a tournament within it, non-tournament aspects of the tournament may require nudgy controls.
There is nothing in particular that pins the multiplayer skill tournament to a particular genre, such as racing or fighting games. Presumably any multiplayer game could have the narrative and gameplay of a multiplayer skill tournament. However, in practice, one finds that only a particular subset of games have realized the multiplayer skill tournament. Those games are 1v1 fighters. There are numerous multiplayer games that one may think are multiplayer skill tournaments, but actually aren’t. I’ll begin by explaining some examples that may seem at first glance to fit the category but actually do not. Usually this is due to the game not satisfying the second requirement: that the game is purely a competition of skill
The first example is the least related to multiplayer skill tournaments out of what I’ll discuss, but it’s still instructive to consider it. Mario Party seems to be an instance of a game that is multiplayer, where the players compete in a game of skill to determine the victor. However, a significant portion of the results of the game are blatantly based on randomness as opposed to skill (evidenced by the constant die rolls). So Mario Party fails to meet the second requirement and so should not be considered a multiplayer skill tournament.
Another example that one may consider is Call of Duty, which features a set of players competing at a skill-based game to determine the victor. Call of Duty fails to meet the requirement in two important regards, though. Firstly, there is no notion of a tournament present in the narrative. More often, Call of Duty is about a single war, or various covert operations, which have far more complicated victory conditions than a single match between players (including civilian casualties, and political stability post-war). Secondly, due to the nature of the cruelty of war, there is an awareness that sometimes even the most skilled soldier is a random casualty of war. Within the narrative of a war game such as Call of Duty, there is an awareness of the possibility of random loss, since war is too complicated and messy. Sometimes the best soldier dies. I will not be considering Call of Duty to be a multiplayer skill tournament because of the random losses and lack of a tournament narrative.
One example that may initially seem to be a multiplayer skill tournament is a racing game. In principle, there is nothing preventing a racing game from fitting the category. If the game is multiplayer, the vehicles are roughly equal in power (however this is defined for a particular vehicle), and the narrative is that of a tournament, the game would fit the category quite nicely. However, this is not what you tend to see in practice. In racing games one tends to see one of two things: sabotage, or unequal vehicles. In the instance of sabotage, one character has somehow tampered with another character’s vehicle, skewing the results of the tournament. In this case, an author should probably introduce nudges to the gameplay to make clear that there is something preventing the player from fully realizing their skill. Often, as well, the different characters have clearly unequal vehicles, making it not the case that skill specifically is what determines the victor. If a racing game avoids these two problems, it would be a good candidate for a multiplayer skill tournament.
From these examples one can see how fitting the mould of a multiplayer skill tournament is a case-by-case basis. From here I will consider a set of games which nicely fit the category.
1v1 fighters are a paradigmatic example of a multiplayer skill tournament. There are many games that fit the 1v1 fighting game paradigm. A few notable examples include Soul Calibur, Tekken, and Street Fighter. Although the category cannot be pinned down entirely, a majority of these games feature two players fighting against each other in two dimensions. There exist a wide variety of moves available to the player, some of which are activated by button combinations, or a specific sequence of button presses. These moves tend to be more powerful. In order to be successful at a 1v1 fighter game, a player must know three things: the powerful button combos, when it’s best to use any particular move, and how their opponent will likely play.
Most 1v1 fighters tend to share a similar narrative basis: a collection of fighters come together to compete in a tournament, where the winner takes all. A prototypical example of this would be the original Tekken, which features no overt story other than the existence of a tournament. While some of these games take characters from other stories, the narrative is more often than not framed in the fighting tournament schema, in which the strongest, most highly skilled fighter is the winner. And since the players are the participants of the tournament, acting as the fighters themselves, the most highly skilled player should always come out victorious. 1v1 fighting games realize this narrative by creating a cast of fighters who all have roughly equal potential for victory, and keeping the game as close to nudge-free as possible.
All of these games share one key common feature: they are all designed to have a cast of roughly equally strong fighters. Due to the difficulty of that task, there is no 1v1 fighting game that is actually perfectly balanced between all the characters, but having a cast of equally powerful fighters is the end goal of the design of these games. Evidence of the goal is the constant “nerfing” of powerful characters, who are made a little weaker, and “buffing” of weaker characters to bring them up to par. The unachievable end state of fighting games is a set of characters all on a par with each other.
We can thus see that 1v1 fighters meet the essential requirements for a multiplayer skill tournament. Multiple players square off against each other, the victor is the one who is most skilled (given that the fighters are equally strong and/or fast), and the central thrust of the narrative is a tournament.
So why does a multiplayer skill tournament require nudge-less gameplay? What differentiates the winner from the loser is supposed to be the better player. Skill is what determines the winner. Let’s consider what happens when a developer introduces nudges that further hinder the player. In this case, the players can tell that they are being hindered from performing at the level they desire, similar to the case of an opponent sabotaging them. The players will feel less like skill is determining the outcome, and so the tournament no longer will feel like a competition of skill. In the case that the developers introduce nudges that actually help the player, then those players who are less skilled will have an artificial boost in skill. This is a problem because if these players should win, it would not be through skill, but rather through the benefit of nudgy controls, similar to the instance in the racing game of one character simply having the best car. Less experienced players will be able to achieve success without skill, to the detriment of the more skilled players. In both the instances of hindering and helpful nudges, introducing nudges into multiplayer skill tournaments is problematic. In order to maintain the narrative consistency of the worlds of multiplayer skill tournaments, in which the more skilled competitor is the winner, the game needs to be unhindered by nudges.
All three of the kinds of games I mentioned share one fundamental feature: they are all games in which the level of competence of the player is a necessary element in the narrative of the game. In trial-by-death games such as Dark Souls, the narrative of the game contains several instances of failed attempts by the player, and so narrative consistency is preserved by having a player transition from being incompetent at a task to be competent and then succeeding at that task. In Octodad, the controls are obtuse enough that a majority of players will be incompetent at the game in the same way as the octopus is incompetent at being a father. No nudges are necessary to realize this narrative. In multiplayer skill tournaments, the differentiator between fighters is supposed to be skill. By introducing nudges, a designer undermines the extent to which skill feels like the determinant of the course of the narrative. So introducing nudges would be counterproductive.
That does it for my discussion on games that are unhindered by nudges. In Part II I will discuss some examples of games that use nudgy gameplay to preserve their internal narrative structure.
 I prescind here from the obvious counterexample of people who have played Dark Souls many times, and so rarely die.
