We're hitting all these bonus tiers that add new areas and races and stuff, which is great! But, I'm also interested in adding depth and replay diversity to already-planned regions & companions. I understand this is a little harder to quantify as a Kickstarter goal ("uh, we'll increase the dialogue tree complexity by 20%!"), but that's the game I'm most interested in. Instead of (for example) having eight companions with eight pages of backstory, hitting a tier and adding a ninth companion, I want to add a page of backstory to the eight already there.
Don't get me wrong, I love me some good exploration, but I'm more interested in finding out something interesting about a character I care about than finding another generic cave. Different kind of exploration, I guess.
Some Torment nostalgia: (skip if you haven't beaten it)
