Marvel vs. Capcom 2

Hands down the best fighting game out there, possibly tied with Soul Calibur 2. You've played the previous games in the series, now get ready for the ultimate. Featuring 56 or so characters to unlock and play in manic Capcom style, you'll recognize all your favorites and make some new ones from the slew of Marvel and Capcom fighters. It plays like Street Fighter 2 on crack and is fast and furious with each character having great signature moves and hypers, dealing loads of damage to everyone. Check this game out and challenge your friends to massive 3 vs. 3 character battles. You won't be disappointed.

Hint: To earn up points the cheap and easy way, put the game into training mode and then turn off the tv or disconnect the PS2 and watch something else. You get about 10 points for every minute by my reckoning so leave it on overnight or while you're watching some movies and you'll have enough to buy loads of characters. You still have to play through to raise your level though which lets you buy new characters.
