I hated this game when it was first released due to their needless change of an already great skill system (via DD). This was compounded by another trip through crazy bad opening dungeon (circa DD). If you managed to get past those two major gripes, the game actually got a lot better. You still were forced to specialize your skills to get any real benefit, but the dual character battles were kinda fun when you got the hang of it.
Still rates as one of my most disappointed gaming moments though (nothing compared to Gothic 3 release), DD was so good compared to BD.
