But was Diablo 2 complex? No. The game basically *told you* where to put your stats. You play as a Barbarian, and find a cool sword, but don't have enough strenght to use it - what do you do? You play as a Sorceress, and notice that you run out of mana too quickly - what do you do? Of course, your first few chars will be imperfect, but it's possible to beat the game with a pretty messed up character.
Hm, you know, I think I can understand the argument that stats didn't influence anything *that* much, so it's not a big loss anyway... well, let's hope so.
