Personally, I liked Oblivion a lot. But then I have only played Arena and Oblivion. I heard that Morrowind's combat was crap, the walking and running speed is so slow. Arena was good for an oldie, though I still have not gotten out of the first dungeon. But then the thing that saves Oblivion from being a crappy game (for you) are its mods. It adds a lot of elements and variety to the game and it also makes it buggy to the point it CTDs after 5 minutes of play
