Rez was originally a quirky shooting game for the Dreambast. It was recently re-released in HD for the xbox 360, and I highly recommend picking up that version, both because HD > SD, and because Dreamcast controller < dead turtle. Also, the game for some reason supports multiple vibrators. So with the dreamcast version, you could buy wired vibrators to put...on your body. I'll let your imagination go wild with that for a minute. On the 360, you can actually set up additional controllers to act as vibrators for you. I never saw the need, but other reviewers think it increases the immersion.
