I just don't see the value in trading them in. I have the original Sega Genesis with the sliding headphone volume knob. Original SNES w/ both controllers. The black limited edition Sega Sports Dreamcast. The smaller ps1 playstation. Slim ps2 2 OG Xboxs and the Xbox 360 ironically I'm playing the xbox more than the 360. Do you guys keep/collect old game consoles?
