True, but this starts getting into developer capability. Nobody expected Obsidian to overhaul the entire Gamebyro engine on their own, the company wasn't designed around such complicated work, it requires specialist companies like id or crytek to push forward a game engine in a significant way. EA forced Bioware down that path when they mandated every company they owned had to use the Frostbite engine, and it destroyed the company since they were a company that always licensed out existing game engines like it did with the Unreal Engine for its Mass Effect series. Suddenly they had to start heavy work on the Frostbite engine just to do complex facial rigging and cutscene animations. 

I just don't know why people think Obsidian was responsible for fixing stupid shit like vendors requiring there be a chest under the ground or the insane ragdoll physics shit that had been around for years at the time.
