Pros: Many playable characters. Many villains. Good multiplayer system.
Cons: Very repetitive. Gets boring.
The bottom line: Overall, a good game. It just gets a little repetitive. But it is worth buying.
The Good
There is many playable characters from a wide variety of Marvel Comics. Also there are many villains throughout the game from a wide variety of Marvel comics. Great game play. Almost no learning curve, within lest than 10 minutes I was playing like a pro. Your super powers can be used extremely easy. Great leveling system. The multiplayer is very good. It has two modes when going through the story. One where you can just play through the story as you would normally. In the other, you choose 1 character and play only as him. You get points for combos, kills, etc. and the scores are tallied at the end of the level and the winner gets bonus exp points. Also, you are capable of playing online multiplayer with X Box Live.
The Bad
The only complaint I have about this game is that it gets repetitive. The world changes and the villains change but the game play is the same as in the last world.
The Verdict
Overall a good game especially if your a comic fan. It can be a lot of fun, especially when playing with a few people. Just be ready for repetition.
