I hated Oblivion but loved FO3. Oblivion is like Fallout 3 but worse in almost every way. The story is implemented even worse than FO3, which was bad to begin with. I didn't enjoy any of the sidequests. The interface reminds me of PC games I used to play back in like 1992. The graphics are worse. The characters aren't interesting or memorable. The world is bigger, but there's less interesting stuff to do in it. The concept of guilds is a good idea but I found the missions to be kinda boring.
It took about 3 hours for me to get hooked into FO3. I played Oblivion for about 15 hours and still wasn't really enjoying it so I sold it.
On top of that, I think the setting of Oblivion is corny and there's nothing in the story or characters that could overcome that like how Dragon Age was able to overcome that for me.
