I agree with Luciferson, the game does make you feel like your in an epic battle. The graphics are amazing, each animation looks as smooth as a babies bottom. On co-op the game is outrageously fun, (thats right outrageously fun), and single player is great, too. I've only played the first gandalf level in single player, but in co-op the game is very strategical, sometimes you have to stop in the middle of a combo just so your buddy can get the potion in front of you.
Oh, all that from the first 4 levels, mmmmmmmm... amazing game.
