Lessee...could be my copy of Tengen Tetris, or perhaps my copy of Earthbound (in box, complete with scratch -n- sniff card). I have a number of hard to find games (just picked up Trapt for PS2, for example), but they're not valuable, per se.
Earthbound? In a box? Wow, give it ten years and you could buy a second house with the funds from that at the rate its increasing in value.
Oh yeah, and I also have Ehrgiez, a Power Stone-esque PS game that features characters from FFVII, but I'm selling that because it's plain awful.
