The vocabulary the whole index is built on.
Every filterable field is constrained to a controlled vocabulary — that is what keeps “hardcore” and “roguelike” meaning the same thing on every page. These are the canonical terms.
Standard progression with recoverable deaths, checkpoints and unlimited reloads.
Strict progression with higher stakes and semi-permanent consequences.
A single death deletes the character or resets progress entirely.
No manual saving or retries. Continuous playthrough integrity.
Procedurally generated, single-life design; no metaprogression.
Procedurally generated, allows persistent metaprogression.
Ranked leaderboards, PvP focus, or scoring-based competition.
Each mode references these by id. Add a variable by appending one object — no migration.
Auto-applied at build from a mode’s mechanics.
