Whats so good about baldurs gate ???

I have never played a Baldurs Gate game before but am just as excited for the release of this game as the rest of you guys.
I can see the potential that this game has but at the same time i dont see what all the fuss is about, can you guys explain why u like this game so much... the details etc etc, what makes Baldurs Gate so incredible for you ?
Why should i get excited ??
Looking forward to the release date to find out.
