what would be awesome I think is if Marvel made a 3rd Ultimate Alliance game which after the awesome first two im surprised it hasnt happend. But if they need a story I think the best one would be Avengers vs. X-Men! The game could be 2 whole seperate stories like MUA 2 with the civil war except u choose to be Avengers or X-Men. Along the way the story's of both teams are pretty much the 12 issues of Avengers vs X-men while also what would be cool is if they added in some of the tie in story's like for example the X-Men's battle with Sinister or the Secret Avengers battle in space against the Phoenix Force. Along the way of the story you lose characters and gain characters such as an avenger you can play as Hulk towards the end, Wolverine and Beast only in some levels as they werent on the Avengers the whole 12 issues really. And with X-Men their whole side of the 12 issues starting with Utopia, to being on the run and finding hope to becoming the Phoenix Five. Then Avengers fight the Phoenix Five in order like the books and while that happens if you play the x-men side you can play as the Phoenix Five and/or X-Men against the Avengers. But once Namor, Colossus, and Magik are down, you cant play them and thats when the X-Men leave and help the Avengers against the final bosses Phoenix Cyclops and Emma Frost. The final levels are bound together then but can only play as either X-Men or Avengers which ever story your doing. You battle Emma, then Cyclops and Emma and then You battle in the final all out battle that would be epic against Dark Phoenix Cyclops and go around the world to the fighting. Lastly the part 2 of the battle is you have Hope and Scarlet Witch and choose two Avengers or X-Men what ever story you choose and finish the game and beat him. It'd be a pretty epic game I think and if they could ever do this Marvel I would buy it when it comes out right away Avengers vs. X-Men would be an epic game whether part of MUA or just a single game on its own.
