Your guilty pleasure game

I think I'm about to start playing Infinite Undiscovery, which is a game I enjoy about 10 times more than I should and in another thread in the off-top forum I remember someone recently saying that James Cameron enjoys him some Resident Evil movies. I'm curious to know which games you guys play and love that you know aren't very good. Don't mention games you enjoy with some sense of irony, just games that you play because you legitimately find them fun.
