Wierd LCD interchangable game system from tiger. The games are all like those little LCD stand alone units, each with it's own screen. There are several versions of this system, the one pictured is this strange head-strap thingy that you wear stuck to your face and the games are like an inch away from your eye. Okkaaayyy. There are also tapetop and handheld (ala GameBoy) styles of this system. I never really liked games like these, even as a little kid. They're fun for like five minutes but then just get boring.
Suprisingly the handheld and tabletop versions of the R-zone seem to sell for about $25-$30, so if you see one cheap it might be worth picking up for resell value.
