Pool of Radiance was terrible. Flee from it. Zero redeeming values.

Planescape Torment was brilliant. It starts slow, but stick with it. It's like playing your favorite novel. The story is that good.

Icewind Dale and IWD2 are excellent fighting games. Fun, replayable, and I recommend them but they are only fighting games.

BG2 is - IMHO obviously - the best computer game of all time. If you haven't played it you must, stop reading this post and go buy it. Now.
