Went though the game twice. I'm sure as, they mentioned, this isn't final code so some of the issues listed may be fixed, others won't be though.
3 catagories Fixable, Won't be fixed, Might be fixable
Fixable
Camera
Numerous times during combat, the camera would just drop to the ground and I could neither see my character or the enemies I was fighting.
While in combat and running away, the camera seems to zoom out a lot, messing up your viewpoint with what direction your heading. Seemed more of a problem in dungeons with enclosed spaces.
The camera auto rotation upon movement is erratic. Sometimes it worked, other times I had to constantly move the camera while moving though the enviroment.
Audio
The sound glitched out numerous times. I lost sound completely switching to a new weapon.
Sound mix during conversations is bad in some instances, particularly the beginning with the gnome.
Graphical glitches
Weird glitches , hard to describe but wasn't normal, if it happens to you, you'd notice.
Won't be fixed
Framerate
Eyeballing it, the framerate dropped below acceptable levels (30fps) numerous times, mostly during combat.
UI
The UI is pretty bad, have seen indie games with better ones, but it's all we are gonna get.
Voice acting/Writing
Just plain bad, I rarely skip dialog in rpgs, and I started doing it by the second npc. I don't know if it's just the acting that's bad or a combo of a bad script/va.
Ze goggles, they do nothing!
Blurry mess in some places, hard to make out any real detail. May or may not be acceptable for the average console game. My view may be skewed because I've been playing one game with far more detail on my pc as of late, and haven't touched my 360 in weeks. GoW 3 looks clearer though.
Player character models
Ugly, surprisingly, after seeing art of other things in the game. Step above Oblivion, which isn't saying much.
Might be fixable
Auto lock on system
Seems very lazy and doesn't seem to work 100% of the time.
I did enjoy the combat, and even with what seems like quite a few negatives, I'll stick pick up the Steam pc version, unless it's loaded with 2 or 3 forms of DRM, otherwise, used on 360 way down the road.
Edit: One last negative, never, ever put an escort quest in your demo, or game for that matter, they are never fun.
