Dont blame the engine when the AI is bad (Score 1)

Of cource theres baulders gate Dark Alliance 2, which is based off dnd 3.0 and runs fine. Not to mention the majority of the problems mentioned in the article refer to AI problems, rather than problems porting d20 rules. In all reality, Diablo 2, which is arguably one of the more succesful rpgs of all time, uses a d20esk system in its calculations.
