This index documents the discipline-level vocabulary used across the games module. These terms describe structural features of games as a category — the building blocks that recur whether you are analyzing card games, role-playing games, board games, or gambling. Topic-specific vocabulary lives in topic-level term directories (card games terms, role-playing games terms, gambling terms).
The distinction matters. A trick belongs to card games. A session belongs to role-playing games. But concepts like player, rules, turn, and game state appear in nearly every game tradition and need stable definitions that are not tied to a single topic. That is what this directory provides.
