Hm, I remember that I once had a Star Wars themed machine that only played, well, a Star Wars game. The bastard needed batteries to function and only costed me like 30 dollars.
Pretty sure that SEGA did a similar treatment for some Genesis games, including Sonic H1, Altered Beast and Dr. Robotnik's Mean Bean Machine (pretty cool game, btw).
My bet with The_Liquid_Laser: I think the Switch won't surpass the PS2 as the best selling system of all time. If it does, I'll play a game of a list that The_Liquid_Laser will provide, I will have to play it for 50 hours or complete it, whatever comes first.
