I would assume that the people who come here are obsessed with videogames. And since there are those who go to the extreme with their gaming habits, I have a question for everyone:

What is the rarest game you own, and the approximated value of it?

I think mine would be:
Dragon Warrior IV, complete in box with all the charts, 84-Page Explorer Handbook, everything, mint condition (box doesn't even have a dent). Approx value: $150US
