I've been playing Marvel Ultimate Alliance for the past couple of days and its now my favorite super hero game of all time, just narrowly beating out Incredible Hulk: Ultimate Destruction. It's like someone picked out all my favorite qualities in a video game (button mashing beat 'em up, super heroes, interesting plot) and created a game just for me.

You get the use all the members of the Fantastic Four, Wolverine, Spidey, Captain America, Thor and even fricking Daredevil. Plus you get to fight in Mephisto's realm, Asgard and the Shi'ar empire. It's a Marvel comic book geek's dream game. Cop this game if you haven't already. 

PS: Can someone explain to me how Google knows to refine the search results for the query for 'Marvel Ultimate Alliance'. I'm guessing this has something to do with Google Co-op.
