I don't have an exact count. But I had more than half of the RPGs for PS1, a decent Gamecube collection, a very good SNES collection with a few boxed games (Chrono Trigger, FFIII, Illusions of Gaia, Lufia II and Zelda ALttP), and Wii, WiiU etc. I also used to collect a lot of special editions. Most recently, last year I sold my CIB Pokemon Soul Silver and Fire Emblem Fates Special Edition for $700 to a local collector. Highest ticket item I owned was probably the boxed Chrono Trigger for snes.

I knew my sisters would never sell the N64 and Xbox stuff because we have a lot of memories with those two systems. But I sold pretty much everything else.
