I am chomping at the bit for the new Batman game. That looks beautiful and if the controls are as smooth as Assassians Creed it will be an amazing game.
Do you have a Game Crazy store near you? Most around the country have had a Batman: Arkham Asylum demo running on either the PS3 or Xbox 360. It is nothing spectacular, though, just an arena where the joker keeps sending goons at you in a gladiatorial style.
As for me, I am currently playing Prince of Persia on the 360 with a smattering of World of Warcraft on the side.
