Batman: Arkham Asylum was a good game and one of my favourite games but when Batman Arkham City was released it blew my mind away. The platform is much better and the graphics are excellent and the storyline is great. More combat moves and the side missions are really good. By far better then the first Batman and that was a good game. Playing online with the challenge modes they have made all the different stages bigger and better and the extreme challenges are brilliant. This game will definitley be in my collection This is a must have game for everyone !!!!
