Having played Oblivion for hundreds of hours I assumed that I'd been everywhere, done everything, and generally had "done" the game. But a few months ago I picked up the Oblivion guide book (can't remember it's proper name) which quickly showed me that I hadn't done squat.
So after emerging from the sewers I pointed my character in a direction I didn't think I'd walked in the past (up towards Bruma) and instantly started stumbling on places I'd never been, characters I'd never talked to, and quest after quest I'd never done.
Holy shit that game is huge
