If you're like me, you think that Katamari is pretty crazy, but these 6 games make Katamari look like the suburban housewife of video games. Take, for example, LSD:
Bumping into anything or anyone will cause the screen to fade and teleport you to another random place. After a while, you might start seeing the same places again, so the game keeps it interesting by doing things like replacing doors with women's faces or filling the walls with eyes that slowly follow you as you walk past.
Believe it or not, that's not the craziest one on this list either.
