I played Arkham Asylum back on the 360 as a kid. But I didn't play it properly until much later. This game works pretty well as a standalone game as when this game was made, the devs didn't know they would be able to spawn an entire line of Batman Games. So, it's more contained. And it shows. The Horror vibes are unmatched. I think the gameplay didn't age well as Arkham City improved on the gameplay by A LOT. Still a Good Game.
