Many ( and I really mean many ) features of AD&D 2, the system used in Baldur's Gate, were completely brain damaged.
It would be better if they used the 3.5 or Pathfinder 3.75
Those two are tried and widely accepted among roleplayers, and they work quite well in a computer game (NWN 2, despite what some people think of it, got pretty much the best combat out of all BG-likes).
It's quite logical considering the 3.5 was the last official version before D&D became some sort of tabletop MMO (read : D&D 4).
