The Sega Zone is a weird little console that comes preloaded with 50 games, including 20 classic Genesis games. 16 of the remaining games support motion control with a strange Wiimote knockoff, if that's your thing. Look for it in the UK this summer for $60, if this in any way interests you.
Admittedly, I do love classic Genesis games. But I also love the smell of gasoline to the point where I find myself loitering around gas stations. Mmmm, BP.
