Kaz: BG2 and ToB rock. I'd reccomend buying it 100%!
Black and White is also a brilliant game.... for the first week or so, and then it becomes overly fiddly and far too annoying to play. I know several people who fell in love with it for a day or two only to get their heart broken.
This is just my experiences with it, so you might want to listen to some others too before you make a decision

Within the jungle of my deepest emotion,
With a coat resplendant in a golden sheen,
Swiftly hunting my tender love,
