Hrhm. Been playing Planescape Torment rather a lot... I like it. I absolutely despise my previous incarnations XO Damn but they were bastards. XO
As for the NPCs (the ones I've already met, anyway), Dak'kon makes me feel uneasy and gets on my nerves, I like Annah a lot, Fall-From-Grace is very nice, Ignus really freaks me out, and Morte's a riot. Though (after going through the memory related to him, how I found him and stuff)... I feel sorry for the poor guy. (Guy, skull, whatever.) I feel really sorry for him. :|

Meh. This is to say, I guess, go play Planescape Torment if you haven't already. It's bloody good, one of the few games which has made me really feel for the characters. Beats the hell out of any other RPG I've played, including Baldur's Gate II. Of course you have to be willing to follow a plot and read through a lot of conversations... but it's really bloody good. It's almost like reading a book, and not playing a game.
