NWN2 is a great game, great story, great NPC's, great gameplay, and lots of ways to finish quests....
...despite the technical performance issues. That's my biggest complaint w/ the game. The game really needs a performance tweak. I had to turn down a bunch of graphical bells, to get it running well on my strong PC. Oblivion runs and looks much better than NWN2 on this rig -- which was a surprise to me. NWN2 looks quite good, regardless -- but not *good* enough to warrant such a framerate and performance issues.
The cameras ain't that great --- I don't like Chase Cam. Free Cam is okay -- a lot similar to cam in BG2. The other cam is good, I think it's called Direct Cam, if you want to keep it always behind you -- a la the SW: KOTOR cam style.
Though, I really do like the Top Down Cam, which I do move around a lot like I did in NWN1 w/ the cam unlocked and all. This cam doesn't bother me, b/c it moves the way I want it, when I want to move it. It doesn't try to correct itself or anything. It moves as I see fit.
