We're looking forward to Batman: Arkham Asylum like it's going out of fashion. The demo is our collective most-played anything this week, with me personally having played it for hours at a time multiple times (and about to do so again), so it's obvious that we enjoy it. A lot.

If you're anywhere near as batty about the demo as we are, and are lurking in the shadows waiting for the game to wander past, you'll probably be wondering which version you want to glide kick into unconsciousness. There are three versions, after all - the PS3 version, the 360 version and the PC version. In an effort to help you out, we've listed the features of the game, including pre-order bonuses, platform-exclusives and just general information, after the break.
