Impressions having just gotten to NW:
The AI is atrociously stupid. No matter how much I tinker with NPC behaviour I cannot find the "Stop being more retarded than Volourn" button. They will run through traps to attack, chug potions nonstop (allowing AoO, meaning more chugging, meaning more AoO), run around changing targets seemingly at random (meaning more AoO). My main character is a bard, if I stop controlling him for a second because one of the followers is doing something tragically stupid the AI controlled bard immediatly spams sanctuary song, then runs around wacking all the enemies on screen, invalidating the effect (if there are any enemies, I guess the AI is in constant fear of ambushes).
In ESF speak, it's like roleplaying a catherder trying to get 4 of the most fidgety inbred stupid cats from point A to point B. It's infuriating, but I'm not sure if it's stricktly the AI, or the AI coupled with making a tb system into rt w/p.
The camera is shit.
There are fairly good dialogue and some choices, but too soon to know if there are consequences. I haven't had performance issues, but the constant loading when you go indoors or something is annoying as the models are pretty dull.
