Well I kind of figured that Tyrael and Diablo had to be in the game. I don't remember who Imperius is. I'm kind of curious what the big plot twist is that is supposed to occur after the skeleton king dies.
But overall, while the story is a bit more interesting this time around, the ARPG genre has never been about story. As rich says, it's about killing things and collecting loot.
