Started playing it myself and overall I am enjoying it. The only bug I'm having is the apparently omnipresent pop in texture bug, but it's not too noticeable. On the graphics side it looks pretty good, although higher resolution textures would've been better. However even with higher resolution textures I still think the Unreal Engine is better. In my opinion Bulletstorm overall looks better than Rage. On the gameplay side, it's good, definitely better than Wolfenstein 2009, or Singularity.
