Me too. I wish Baldur's Gate had a turn-based option. I know, however, that others have argued here that by trying to implement both realtime and turn-based, neither were particularly good. I'm not a connaisseur of combat, so I don't know these things.
Of course Arcanum could be improved in many ways, but my only solid piece of negative criticism is actually that all the charcters look funny when they are running.
They looked funny to begin with. The characters looked just horrible but the game itself was still good though.
