That is why I am always for CRPGs use their own original system made by the developers instead trying to shoe horn a PnP rules system to a computer. Its never going to happen to a satisfactory level. That is why games like Fallout, Fallout 2, and Arcanum will always be superior to games like KotOR, NWN, and V:TM.
If they could do KotOR and KotOR 2 story in an original rules system I wouldn't be whinging. :D Well, maybe I would but not as much.
