Metagame
A metagame, broadly defined as "a game beyond the game", typically refers to either of two concepts: a game which revolves around a core game; or the strategies and approaches to playing a game. A metagame can serve a broad range of purposes, and may be tied to the way a game relates to various aspects of life.: 2,14
In competitive games, the metagame can refer to the most popular strategy, often called a game's meta, or preparation for a match in general.
In tabletop role-playing games, metagaming has been used to describe players discussing the game, sometimes simply rules discussions and other times causing the characters they control to act in ways they normally would not within the story.
