When it first came out, I was sort of impressed. The story of an occupied America is easily one of the most intriguing stories I've seen in gaming. However, the graphics aren't too impressive, the campaign's too short, and the characters aren't very memorable. Multiplayer is decent, though.
If you're planning on getting this, try to get it new, since buying it used won't guarantee you an online pass. But if you're strapped of cash, get it used.
Sometimes I like to pretend I'm a meatball.
