Summary: this game is fun to play with a decent story but it is easy too short. I started playing it again just to see the other powers available and to pick all the brotherhood choices. the powers are well done but it really doesn't matter if you choose x men or brotherhood because you pretty much get the same game play with a few different missions. The graphics for this game look like it was made for the PS2 instead of the PS3.
Summary: Marvel tried really hard with this game, and kind of failed. I will admit this was a big step forward for them in the X-Men field, but the poor quality and run-around nature make the game hard to enjoy. The "Factions" thing is pretty much a joke. No matter which side you choose, Emma Frost still leads you around the help the X-Men, and the battles are still all the same.
Summary: I think that the only bad thing about this game is that there are other action/rpg games that have show us what a great combat system and graphics the PS# can deliver. I cannot say the game is awful because is not true, neither that I did not enjoy it, because is really cool to play a "nobody" that meets the entire X-Universe!
