When I was a kid, starting at a very young age, I had amassed a collection of about 150 NES, SNES and Sega Genesis games. The games, and my consoles, were like priceless treasures to me.
At some point, I brought a selection of games to my cousin's house (all my best games) because my family was staying with his for a while. Somehow during the time we were there, he sold them all
He grew up, got a really hot girlfriend last I saw, and got drafted by the Kanses City Royals. The rest of my games were sold by my little brother-- for drugs I assume.
