I just got this game. I played the good campaign on casual. it was really easy except for LOTS of tight spots were u barely make it. throughout the battles u have to adapt to what your team needs you to be as a class to win. the graphics are ok, and the feel of the massive battles is great, but the evil campaign is way too hard, even on the first level.
I would reccomend the good campaign, and if u had 2 controllers to do co-op. i dont have LIVE yet so i cant tell u about multiplayer. idk if u would like it or not...
