Holy Crap! Now THIS is what Neverwinter Nights 2 should have been. Amazing. And yes, the engine is smooth, and responsive without the stuttering of 'other' games we've seen. I am going to run my Rogue first. (Love my Thief games)
The atmosphere is really something. It really does bring back memories of Baldur's Gate. *sigh*... finally.
Bioware, this will be RPG of the year. bank on that!
More soon!! I will mess with the toolset after I beat it, and maybe make another Undermountain mod!
If this had multiplayer, it would be perfect. But hey, maybe in an expansion pack, eh?
