Ok, so didn't have a TON of time to play (3-4 hours), but here is my feedback from that.
1. Did the quantity of starting attributes get reduced? It feels like my characters had less when I started the game than when I played the EA. I could be wrong, just felt that way.
2. Less control over origins characters. I was a little irritated that I couldn't pick their initial skill and attribute distribution. I know I could do that in the EA, and instead, they decided to level themselves for the levels before recruiting them. So, instead of Sebille having 2 points in thievery like I wanted when I told her I needed a rogue... she had 2 points in sneaking... which I really didn't want her to have. I wanted her to have 3 points in thievery by level 4, and now she will only have 1, which isn't enough to do anything.
3. Books. Christ almighty, they are so much more expensive now. Don't dig that. I literally don't have enough money to afford the skills I need to do better in/survive combat. And because stupid Sebille decided to put her points in sneaking... I can't steal those books for a while either.
4. The voice acting. I didn't care whether it was in or not, but it is good.
5.) Happy that the environmental effects seem to have been scaled back. They seem much more reasonable in both duration and scope.
6. Retaliation/retribution got nerfed? I think that they only increment by 5% now, which is fairly negligible.
7. More difficult to find hidden stuff? Things which I found readily the first time, seem to be much more difficult this time around, though I will invest more in wits and see... or not

That's all I can think of right now- round 2 time!
