I've never actually had a written outline. I just have a general idea for where the story should go, but other than jotting down a few notes, I don't set anything in stone because the story changes chapter by chapter.
Kingdoms of Amalur: Reckoning for the PS3. I've played through it several times now and it's a great experience each time. The very definition of a hidden gem. I'd recommend it to anyone who enjoys fantasy games.
