BG2 is the best game i've played in the RPG side of things. The story is fantastic, and they gameplay as well. The game is massive (even without the TOB exp) and will keep you going for ages.
If you play it long enough to see some of the story unfold, you'll be hooked! <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
Back on topic:...
No one should be put off by the "Turn based" or "AD&D" side of games. Like everyone has said, you won't notice the turns, as it all happens in real-time, and the AD&D rules are dealt with by the computer.
