Batman: Arkham Asylum PC. I'm at 51%, but I managed to pass the Batcave without activating an important cutscene trigger near a cliff. I am now stuck in a glitchy Arkham with missing stuff everywhere, and the only way to get into Botanical Gardens is to start the game all over again. Hooray for autosaves.
Pro-tip: Stay away from the pre-release leak. It's awful.
Edit: Disregard that,proper better crack released. Guess I'll just have to replay the game on Hard.
