Not too bad
Here, the ability to influene people in any fashion really adds a great effect to the game. You can ambush your opponents, attack them in the locker room, manipulate them, give them a nice show of support before a match, call people out, and even interfere in a match. All in all, I'd have to say the options are pretty much unlimited as to what you can do.
The game does have a tendancy to get repetitive after a few seasons but I never seem to get too bored as I just create a new wrestler or make new alliances with the one I have.
The graphics aren't too bad, but still have some quirks when they move around. The ability to create your entire entrance is pretty good, however not quite as in depth as Day of Reckoning 2 for GameCube. One of the best features is the ability to import your own music from a ripped CD.
All in all, this game isn't that bad when you look at what else the Xbox has to offer for wrestling games, and if you're still not sure, rent it before you buy it.
