Who can forget the talk with Sovereign?! That's one of the best scenes ever, and then the fight with one in 3 where you approach and talk to it after. Some of the best game sequences ever written. Period. And replayability is there. You can try all of the other conversation options the second time through with a totally different class and play style. Unbelievable how much they packed into each game. I actually enjoyed their multiplayer too. I had fun unlocking and leveling all the different characters. Kinda grindy like this, but still good fun with a good team.
