Obviously, you have never played Morrowind. Morrowind despite a few things, was the last ES game that really maintained the real hardcoe elements of rpg. Oblivion was a "light" rpg that was enjoyed by many. As for the other poster that said that Morrowind hasn't copy Oblivion's gameplay. well, duh, guess why?

I have played morrowind. During spring break a few years back, Morrowind was one of the only things I did, besides box, sleep and eat. What I was referring to was its gameplay mechanics. Not quite as many, in that regard. there was more stuff to do though
