All over the damn place. My most played titles go in a couple of stacks next to their respective consoles. Least played, past gen or finished games go on the shelves. Then I've got a bunch in my closet and a few in a big drawer. It's as organized as can be with the space I have to worth with. This is part of the reason I wouldn't mind going pure digital, not only switching between games on the fly, but I don't have the space for a dedicated gaming room.
