I've been playing the german version of Darkensang and here's my oppinion, in case anyone is interested:
Excellent game. The graphics are nice, there's all sorts of nifty details, you can craft and brew various items and there's a lot of skills to learn, the quests and nicely done. The inventory system is great.
You can't edit the characters face (minor nitpick)
Anal copy protection that can cause terrible bugs (like critical quest items or characters not appearing)...or maybe it's just bugs.
Thankfully, all save games are databases one can edit ones savegames to fix the issues. Lets hope the english release is free of this.
All in all, I'm very satisfied with it
