Arkham Asylum started it all, it is quite revolutionary.. especially for being a sleeper hit at the time. This game has been talked about a trillion times now, so I'll leave it with my major issue. My goodness, the damn BACKTRACKING, I must've walked through the same area at least a thousand times on revisit. Ok one last thought, the scarecrow sequences were so ahead of their time, truly ridiculous in a great way.
