1) Linear compared to NWN1? Hah!
2) UI is great, I have no problems with it. Can't understand why so many whine about it. It was little bit hard for very beginning, it did not took more than 2 hours for me to get used to it. Now I actually like it. 120 quick slots is great thing
4) They are ok for me, not best ever but ok
5) I like more NWN2's spell effects. Both games have great spell VFX IMO
10) This is 50-50. Items being different sizes adds some "realism" to game, but its annoying to organize your backpack over and over again. Besides, you can still carry huge amount of greatswords for example in NWN1, so it's still not realistic, which is just good thing. So argumenting "its more realistic!!!" is just stupid.
11) Can't understand this either. They're not best ever but good. And not ugly IMO. Before CEP I could find only few good faces in NWN1, so go figure.
12) Interior areas in OC are fabulous, especially that (I'm talking about "normal" areas such as houses)
14) Load times are far from long with me, and I have weaker system than you (minus processor)
16) I don't care about multiplayer much, but this indeed may be true problem. But I don't care about MP so it doesn't matter for me. Of course I hope this is getting fixed in some future patch
31) Not a real problem for me. Minor minus but that's it.
37) Small annoyance, but how can you find that as "game killer"? Besides, propably someone in the community has already made nude skins for the game...
42) Uh... gliding over ground? Never happened for me. Animations are ok, I hated them first but now I like them. Weird
edit: Many, many spelling errors. There must be more but I'm too tired.
