Got this the other day and while its GFWL which is shitty the game itself is superb for some nice gameplay. Story isnt too short and plods along at a nice pace. Graphics were nice on my card (9800GT) and pretty much maxed out. There is an assload of challenges and achievements for those of you with OCD, the challenges have extended the life of the game for me and Im on my second play through which is rare for me.
Voice acting is pretty superb with Batman pretty gritty and the Joker superbly done by Mark Hamill. Its fairly well influenced by the Tim Burton movies and style and in general works with a nicely dark flavour.
The game has RPG elements in that you earn points for fights and achieving mission objectives, once the rising threshold is met you can unlock one special ability or an upgrade to a pre-existing gadget.
There is some downloadable content at the moment in the form of two additional challenges (you get 20 odd as a default) with another DLC coming out at the end of this month iirc. Challenges com in the form of fights or 'Predator Challenges'. The fights are self-explanatory and they come in waves of henchmen, some wielding weapons.
The predator challenges are a reflection of some of the best parts in the game. These involve dispatching henchmen while running around undetected taking them out one or two at a time.
Anyway its out on the PS3, XBox and PC. Probably the best superhero game there has been, certainly the best I have played though I havent played much. Characters in the game are Gordon and Oracle, Joker, Harley Quinn, Zsasz, Killer Croc, Scarecrow, Bane and Ivy...feel like I have forgotten one. Wont go into any spoilers other than that...
