Great post, I've been wondering about BD myself, now that I know there's a demo, I'll definitely have to check it out one of these days. In DD I like how you can (most of the time) neglect an early quest and come back to do it later if you feel like it, or conversely jump ahead to a "later" quest if you're up to it. But then sometimes knowing all the quests makes the quests seem more "limited" even though there's a bunch of them. With the act system, I'd probably feel pressured to do all the quests in one act before moving on. But maybe I'd like it being broken up like that. But hey, if it's a Divinty game by the people who made the original DD, it can't be that bad, right?
