Yeah, I loved oblivion when it came out too, when I was younger and it was newer.
I think I know when I started really liking morrowind more than it-
One time, I had no internet for a while, so I played morrowind on my xbox, and REALLY got into roleplaying it, putting myself in the world.
I actually decided one particular, totally unimportant NPC was mai waifu and visited her every day, and built a little shrine of flowers and nice potions behind the counter with her.
Ive never even beaten the game, but I could get into its world much better, and it was much more interesting to do so.
