The gameplay policy of Megami Tensei Wiki outlines how gameplay information should be covered. This page also explains the usage of stat table templates and skill data modules.
General
Gameplay coverage on the wiki should not be written as game guides and should not cover strategies, tips, or walkthroughs. They should only provide explanations of game mechanics or document essential data. Relatedly, their content should also avoid the use of "you" and other forms of breaking the fourth wall. Use of "the player" or "players" is appropriate when detailing mechanical or other out-of-universe gameplay information. In which case, "the player" or "players" must always be used over "you".
Gameplay Sections
In many content pages, the Gameplay section covers any gameplay-related information pertinent to the subject. This can include stat tables for playable characters or Demons, encounter lists, item lists, shops or other local services, etc. The Gameplay section is usually one of the first sections on most pages, allowing users to readily find gameplay information without having to scroll too far down or through potentially spoilery sections below.
Each game covered in this section should be given its own Level 3 subsection ===Level 3===. Remasters or enhanced ports can have their own subsection if there is substantial difference from the original's gameplay information to warrant its own coverage, such as the addition of new mechanics. Otherwise, a tabber can suffice for minor version differences, such as differing stats for stat tables or other lists.
Gameplay Pages
If a subject's Gameplay section has over five subsections, particularly with stat tables or other intensive documentation, then the entire section's contents should be split into a separate Gameplay page. These pages have the Gameplay: prefix, such as Gameplay:Jack Frost or Gameplay:Ann Takamaki. They are linked to using Template:Gameplay {{Gameplay}} in the subject's Gameplay section.
Gameplay pages provide a dedicated space for documenting thorough information while keeping the main page brief. Gameplay pages can further organize its contents into series sections. For example:
=={{Link|Series|SMT-}}==
==={{Link|Game|SMT1}}===
==={{Link|Game|SMT2}}===
=={{Link|Series|P-}}==
==={{Link|Game|MIP}}===
==={{Link|Game|P2IS}}===
Characters with Social Link information in the Persona series should be given their own Gameplay games due to the highly comprehensive nature of this mechanic. See (Section Name) for more information.
Stat Tables
Stat tables are specialized templates used to display statistical information about playable characters, Demons, Personas, etc. This can include stat parameters, weaknesses and resistances, skills, passive traits, victory spoils, location information, and whatever else that is pertinent to the game and subject. Because of the specified nature of stat tables as well that games across the Megami Tensei franchise can vary greatly with their mechanics, each game has their own dedicated stat tables. A game may have separate stat tables used specifically for allies, enemies, bosses, and others depending on its individual needs.
Category:Stat Table Templates has a full list of available stat tables.
Stat tables have a range of information parameters that will display formatted data when filled. Any information added should be sourced from the games wherever possible, such as from a stat screen or from data-mining. Information can also be sourced from official guide publications as well; however, be aware that even some official guides have also been known to contain errors and may not always be 100% accurate. It is therefore recommended to cross-reference any sources used.
Skills are added differently. Skill information are stored in modules, which are called into the stat table and automatically adds the appropriate data. See the Skills subsection for a full explanation.
Information added to stat tables should be kept concise wherever possible, being no more than a sentence long. At times, there may be complicated information that would otherwise become too lengthy to explain within a stat table. In such cases, the information should instead be presented outside of the stat table as a short sentence or paragraph. For example: In Shin Megami Tensei, Fiends have a 1 in 256 chance of spawning on specific tile coordinates in dungeons. Because of this complexity, their encounter location should be explained as a paragraph before the stat table and not within it.
