I had an untold amount of PS2 and gameboy advance games dissapear around 2008, which is pretty much the point I stopped playing those consoles entirely and moved to the 360, PC, and PSP.
Huge collection, an entire childhood worth of games I bummed off my parents, lost like half of them, sold the other half one day. That was a good day, I got a huge bag, rounded up every single old game I could find, gave the bag to the guy at gamestop, got 400 bucks store credit xD. took me a year and a half to burn that money.
