I'm considering asking for the game for my birthday early next year or buying it, either or. I've seen some gameplay, and it looks pretty cool. That being said I know just about nothing about the game. Something about heaven, hell angels, some dead Diablo guy and some angel named Tyrael. The girl named Leah seems important. I read she has some sort of connection to Diablo?.....And that's about it. To the point, is it ok to jump in here? I don't want to be totally lost, or should I play the other two first. Or someone could give me a somewhat brief rundown.....thanks.
