I loved Marvel Ultimat Alliance for the Wii, mostly becuse I am a marvel fan anyways. This game goes into a lot of the best comic book story that there is. They did throw in some of there own stuff but it's not bad or Marvel would't let them do it. They also did a good job on making very different super heros come together. On the down side you don't get every hero that you would like, I some that I wanted to see were The Punisher, some more of the x-men, and more difficult bosses like the juggernot. Some would say that the line up is fine as it is and I some what agree that it is a good line up.
The best part by far is how well it works on the Wii it is one of the best interactive games out for the Wii I wish that more games worked as well. If you get lazy though you can always just use the buttens but it is harder than moving the remote. becuse it takes more time go through the super powers. There is a down side to how easy you can master some super heros. The game can start to get boring unless your playing on the Hard level of difficulty. If you are thinking about getting it you should its a good game and the story does'nt get boring.
