it is not worth buying.
now that i said that i will do my best to say some more stuff about game. it has a very lacking story, and the story seems that it is much the same. the roster gets you more of a choice wich seems very intriging, but you can only chose so much of them most of them are for playing with a friend and not for story mode wich really takes away from the game. the out side interfierse is just annorying, and thats not even that start of it. half the time you are just trying to become a legend, yes you heard me right you can become a legend. wich when it happins it is just a let down in its self.
so all in all play at your on risk.
