I found this convinience store in my city, that has some old sealed games (ps1, saturn, snes, mega drive, mega-cd, game boy). Its owner used to have a gaming store, and some 10 years ago he closed it, but he brought all the remaining games with him. It seems that he has 2 sealed copies of Super Metroid (Big Box, pal version). How much do you think these go by these days?
I'll try to take some pictures these days, just to prove it.
