Quite a few. I haven't finished Planescape nor Baldur's Gate due to game breaking glitches in both, and I don't feel like playing through them just to get to that part again (I'll eventually go back to them because they're great games).
Yea I just started oblivion and Im exhausted after 2 side quests. But I really like the game so I think I'll just blast through the main story and wait for skyrim.CrashBang said:FFXII and XIII, Fallout: New Vegas, Oblivion
With the FF games it was purely because they sucked. With NV it just wasn't what I expected; whenever I was playing it I wanted to be playing Fallout 3. With Oblivion I played that game for like 6 months straight, did every side quest, every guild, everything but the main story. By the time I'd done everything and was ready to tackle the story, I was exhausted and just never went back to it
