Years ago a friend of mine who worked for Chessex (a game distributor) gave me 1st edition copies of Roborally and all the expansions over the course of 3 birthdays.
About 4 years ago some jackass stole my car. I eventually got the car back (and then traded it in) but they'd cleared out the trunk...the trunk in which I'd placed my beloved Roborally games after a night of gaming with friends.
Flash forward to this year's Origins. I'm perusing a dealer's booth and I see these 1st edition copies going for 150 to 200 dollars a pop.
...i think i openly wept right on the spot.
