Now that I finally replayed it, I will say this game has mainly two things over its sequels: side-content and atmosphere. The side-content is actually rewarding because it gives you insight into this universe and the whole game has a rather dark and disturbing atmosphere, which is more or less appropriate for the game's setting. You already know the combat and predator mode are sick as Hell so that's all I'll say about it.

Not my favourite Arkham game, but it does enough to distinguish itself.
