I switch between Oblivion, new game X, Fallout 3, new game X, Oblivion and so on. For some reason, no other developer seems to be able to catch my interest as much as Bethesda.
Just created new character for Morrowind, I'm playing that game since early summer 2005. I've tried Oblivion again not that long ago but I lost interest after few hours. I might try to play again, maybe with another character.
