Why you should buy MvC2:

1. Huge variety in 56 playable characters (of whom I don't even recognize half!).
2. Use cool Marvel and Capcom favorites like Spidey, Venom, Hulk, Captain America, Wolverine, Rogue, Morrigan, Jill, Mega Man, and Strider.
3. Fast 3-on-3 tag action with ridiculous combos... fun at parties!

Why you shouldn't buy MvC2:

1. No Xbox Live support (you could pick up Street Fighter vs. SNK instead).
2. A rehash of older Street Fighter games (with shockingly little in the way of improvement for the Xbox).
3. Takes a while to unlock all the characters... better be patient.
