From the PlanetXbox360.com feature review:
"The Marvel universe, and all the characters involved, has become a mass-market subject for both moviemakers and game designers over the past five years. When the original Marvel Ultimate Alliance was released onto the public it made waves with both action/RPG fans and Marvel enthusiasts. Developer Vicarious Visions and publisher Activision are looking to strike gold again with the release of the first sequel – Marvel Ultimate Alliance 2, which crashes into stores today. The franchise has undergone a lot of changes over the years from X-Men Legends to the next-gen Ultimate Alliance but the one thing that has stayed the same is the incredible attention to detail regarding all things Marvel. After a three-year development cycle we were really hoping to see a polished, upgraded version of the first game. With Ultimate Alliance 2 we got all that and more; the final product being one of the best games of this type that is available on the market right now, something all Marvel fans should play without thinking."
