Amazing. Do recommend. One of my favourite games for many reasons:

Story - a great story is present in the first installment of the Arkham games. You roam Arkham Asylum, the mental institute situated on an island not too far from Gotham City. Baddies keep trying to ruin your night and as Batman you need to stop them.

Gameplay - The combat and flow of the game is smooth and amazing. You actually feel like Batman while pulling off amazing combos and using all your gadgets that are at your disposal.

Graphics - Such a turn on. The graphics hold up well. The whole atmosphere is almost perfect for the setting.

Length - I found the length to be great as well. Not too long not too short. You won't get bored because you keep unlocking new gadgets as the story develops.
