Marvel vs Capcom 2

"The coolest part of the game's one player mode is its cast of fighters, which at 56 characters (many of whom need to be unlocked) is larger than ever. The list includes the previously seen likes of Ryu, Ken, Cyclops, Wolverine, Iceman and hyper-cute Mega Man, but Capcom's also gone about giving us newbies such as Jill Valentine of Resident Evil fame, Tron Bonn, of Mega Man Legends fame, and Amigo of…. uhh, I think Amigo is one of the few original characters in the game (please correct me if I'm wrong)."

"...marks the return of the button masher... Another great 2D fighter from Capcom."
