I've never played a game like this, but it's not too complicated…
Has anyone ever played a game where the “Over map” of a turn based JRPG (let's say pixel) is a chess board and the main enemy boss, already established in the prologue takes another province on the map after every JRPG location the player visits?
You can do things within the story to avoid danger like “hiding” or "out maneuvering" special enemies, lets say “knights” or “bishops” these are bosses, . But basically random “SQUARES” in the game are story beats on the map and you're fighting over these locations against the AI BIG BOSS (the King piece) moving one step at a time.
(To be clear, within certain chessboard squares are WHOLE DUNGEONS and QUEST LINES.)
Is this a thing?
