Nice game
Really nice game to play with your friends, good selection of heroes and specials(you can combine heroes' special abilities).RPG elements added very nicely.
The co-op and online are awesome.
I didn't like the story at all, seems way too cheesy and not creative.Game could use a bigger roster of heroes.Haven't experienced any bugs so far.
Overall nice game, recommended purchase.

Good game for new Marvel Fans
I would have given it a 5 star rating if I had not played the first installment. Marvel Ultimate Alliance was a great game... it had a really long line up of characters that you could select from, and the fun factor was also good. That was a game for classic Marvel fans. This installment is good too... except the number of characters seems far more limited than the previous one. The good thing about the line up is (spoiler alert) that you can select some of the Super-Villains. The in game graphics have improved as was expected, and the cinematics have also increased. I especially liked the trailer for the upcoming Hulk Planet series. Lastly, the really cool new things about the game is the Fusion attacks, and the online gameplay. For people new to the Marvel games, I highly recommend this, but don't forget to get the first installment as well.

Number 2 in more than title
Despite adding new fusion attacks, this title seems to be a step back. Call it the move to casual gaming, or the move to a new developer, but rather than being the incremental improvement that the series (including x-men legends) has previously displayed, this title is simpler. Its still fun, and the storyline is good for fans of the civil war events, but its not a must have if you have played any of the previous games.

Fun...
The game is fun all around but it does have it's drawbacks. This iteration of MUA seems kinda dumbed down, from the item pickups being replaced with team pickups to the graphics and roster, it doesn't seem like previous iterations. Not to mention when you're playing with a group of people it's often hard to know who's who, even with a colored ring around you and I play it on my 42" so...
But even after all it's faults the game is fun to pickup and play and the story (while it's not the best) is still pretty interesting.

Not bad
Pretty good multiplayer game. Graphics not so great though.

I think the first game was better.
