I find that the best parts of Arkham Asylum are twofold: the Metroid-vania structure of the experience, and how the rest of the gameplay systems fit so well into that structure.

Personally, I can't see that brilliance coming through in a quick demo.

it doesn't matter if the gameplay is same as in arkha asylum .. This game is waaaaaaaaaaaaaaaay better than those first person shooter games ...trust me guys i bought many first person shooter games they are all same ii dont even play those games now and never gonna buy first person shooter games .... Arkham city all the way baby
