Rez for the PS2 and Dreamcast was a very quirky game. It made the grand claim of "taking you to synaesthesia" (synaesthesia being the neurological mixing of the senses), through using sight, sound, and rumble in sync. They even brought out this thing in Japan called the Trance Vibrator, which you would sit on to enchance the "rumble" aspect, thus bringing you deeper into "synaesthesia". It's quite a surreal experience playing it, although underneath all the babble, it's basically a very simple on-rail shooter. And one that you could complete in about two or three hours.

But, it's more of an "experience" than a game, and for all it's length; what an experience. It can induce a trance like state quite easily, with it's hynotic visuals, pulsating techno music and rumble all moving in sync. It looks like turd in screenshots, as the graphics are wireframe, but it has to be seen to be believed. I remember it wasn't recieved that well by critics, and it only sold something like two copies. Though, credit to it for attempting something different in this world of GTA clones and samey "genre" games.

Rez, I salute you!
