Oblivion. My little brother downloaded it onto the xbox's hard drive and got bored damn fast because of the slow pacing so I started playing it, got turned into a vampire, went back to my last autosave and never slept again trying to do the fetch quest without actually being a vampire and then stopped playing because I can't pick locks for shit! It sits on the hard drive in case I get bored but even then I just don't play it and have no reason not to.
