I don't really have any that I LOATHE. I have a few games I started and never continued because of how bad I was or how much I didn't enjoy the first few levels (Metal Gear Twin Snakes, Legend of Zelda: Phantom Hourglass) or games that I was so incredibly dissapointed in despite the fact that I played them to the end just so I could say I beat them (Star Fox Adventures, Metriod Prime 2)
