Diegetic Consistency

That depictions of a game world only contains the visual elements that are thematically motivated.

Diegesis is the presentation of the elements in a game world. However, games may need to provide more information due to their systems containing more information than just the game worlds and when this occurs designers may need to question the value of having Diegetic Consistency or showing this information within the reference system of the game world.

Examples

Tabletop Roleplaying Games such as Call of Cthulhu, Storytelling System, and Hârnmaster can have Diegetic Consistency relatively easy since it is the game masters and players themselves that describe the world. Challenges to upholding this consistency can come when system terms (such as hit points, character levels, skill levels, etc.) are mixed into the descriptions or when disagreements arise on what is actually part of the game world or not, or what actions are possible to do or not.

Diegetic Consistency is striven for in many Live Action Roleplaying Games given both the effort to produce the artifacts and props used in these and the effort in enacting bodily the characters and actions of these game (for several days in some case). Examples of LARPs that put especial focus on this, that can be said to aim at a "360 illusion", include 1942 – Noen å stole på and Trenne Byar. The related category of Alternate Reality Games, e.g. Prosopopeia and Conspiracy for Good also have this type of design aim.

Left 4 Dead 2 has a realism mode which increases the difficulty of the game by making the game have more Diegetic Consistency; this is achieved by removing nearly all of the glowing outlines that help players locate other players and important game items even through walls.

Using the pattern

While an obvious requirement for having Diegetic Consistency is that the design elements that represent Game Worlds, e.g. Tiles, do not break the diegesis, a more common problem with making Diegetic Consistency possible is to avoid Non-Diegetic Features such as Geospatial Game Widgets (including Reward Widgets), Extra-Game Consequences, Extra-Game Information, and Tooltips. HUD Interfaces may be necessary to avoid as well, since they are not thematically consistent with all themes and are Non-Diegetic Features if an assumption existing that everything shown on a display should be presented the Game Worlds. Power-Ups share similar problems but mainly since they so clearly affect gameplay. Game State Indicators, e.g. Lives and Scores, do not have to be presented within Game Worlds but having them in any form may start making players perceive other game elements more from the perspective of a game system than a diegetic setting. A second requirement is to not make to strong use of Diegetically Outstanding Features since they may be experienced as not being diegetic. Given the right content in this way, Diegetic Consistency can be easy to maintain during gameplay if Dedicated Game Facilitators are used to present Game Worlds. This cannot be guaranteed in Self-Facilitated Games but a solution, which puts the responsibility on somebody else, is to assign the task of portray Game Worlds to Game Masters. Related to this is the issue of Out of Character Conversations: these may disrupt Diegetic Consistency but the risk of this may be mitigated by Game Masters or by introducing Communication Channels.

One of the problems with providing Diegetic Consistency in Game Worlds or Levels is related to size since thematically these should often be larger than is practically possible to design and implement. One solution, which risks breaking Thematic Consistency instead, is to make use of Inaccessible Areas and Invisible Walls since these can allow games to present an Illusion of Open Space and thereby larger Game Worlds than are actually possible to visit. The use of Levels can be used separately or together with these since the Levels can by having different themes and styles imply that not only intermediate areas exist but also others not yet seen. Warp Zones can be used to provide Diegetic Consistency when Game Worlds do not have the same spatial characteristics as the medium in which they are presented in (a common example, found for example in the Civilization and Hearts of Iron series, is to show spheres such as the Earth on 2-dimensional surfaces such as computer screens). However, they may also break Diegetic Consistency if the zones themselves are not part of the Game Worlds or if they point of other areas that are not part of the Game Worlds.

While Diegetic Consistency is primarily about removing the presence of Non-Diegetic Features, not all parts of Game Worlds should actually be directly perceivable. This fact makes the use of Abstract Player Constructs, Characters, and Inventories help maintain Diegetic Consistency. "Sticky" Switches are related to this since they provide diegetic ways of showing states that otherwise should be hidden to maintain Diegetic Consistency.

While considering Diegetic Consistency, it may be worthwhile to also consider Thematic and Temporal Consistency since these also relate to the aesthetic experiences games can provide. It may for example be more important that the diegetic elements that exist in Game Worlds behave thematically consistent to each other than that everything in the game environment is diegetically present. One area where Diegetic Consistency and Thematic Consistency affect each other is creation of game objects in large worlds; the common diegetic requirement of game worlds be large creates thematic requirements of populating Game Worlds with many game objects.

Diegetic Aspects

Diegetic Consistency is a completely diegetic pattern.

Interface Aspects

The choice of Focus Loci easily affects Diegetic Consistency - Avatars and Units can may maintain it while God Fingers break them. Controllable Cameras can break Diegetic Consistency even it they cannot be seen (an exception to this is found in Super Mario 64 where the player's camera is diegetically presented and carried by the character Lakitu) since moving into corner etc. can make the presence of these non-diegetic entities noticeable.

Narrative Aspects

Due to the Freedom of Choice they give players, the possibility for them to engage in Enactment, Roleplaying, and Storytelling can make Diegetic Consistency break if non-diegetic elements are introduced; this is often mainly a potential problem in Multiplayer Games.

Consequences

Having or not having Diegetic Consistency quite naturally affects how players perceive Game Worlds and Levels. Having Diegetic Consistency is a requirement to be able to have Thematic Consistency since any Non-Diegetic Features automatically also break a theme in the presentation of Game Worlds or Levels.

Since Live Action Roleplaying often tried to create complete and plausible physical environments in which gameplay can take place (especially in the Nordic tradition of LARPs, Diegetic Consistency is often more important to these game than other to the point that the pattern modulate the possibilities of the Live Action Roleplaying.

A rewrite of the pattern Consistent Reality Logic that was part of the original collection in the book Patterns in Game Design. Significant parts of the original pattern is however now part of the pattern Thematic Consistency.
