There's so much stuff to do in Skyrim, much more than Oblivion.
Yup. Really it seems to boil down to http://oi49.tinypic.com/2q36fpj.jpg
And just to clarify, I didn't start with Morrowind, but Oblivion, which I poured I don't know how many hours, days, weeks even into. I still have it too, and I was enjoying it even up until Skyrim released. Right now, the only reason I'm not playing Skyrim, is because I'm just waiting to see what the DLC is going to be before I invest a lot of time and planning into a new character. I don't know if that even makes sense... BUT HEY! That's what I'm doing, I love the game, and yes it has its flaws, but if the game itself is not your cup of tea then you could always just go back to a previous title, or wait a year or two then play it with all the official DLC's.
