While it would be nice to have more available characters, Capcom vs. SNK will keep you busy for a very long time, mastering the nuances of the fighting engine and unlocking the huge amount of hidden features.
Put simply, this is the best 2D beat-em-up that we've played on any format so if you're a fan of the genre and choose to veer away from stunning 3D fighters like "Soul Calibur," this is the game for you.
Capcom and SNK fans will be wettin' their pants for this one -- everyone else (including fight fans accustomed to more sophisticated graphics) will find this tepid at best. Marvel vs. Capcom 2 is a much more exciting game.
if you're looking for an accurate match-up between the two companies, forget it. For the rest of us though, Capcom just delivers some good, old-school 2-D fighting action, and we all need some of that.
