I currently own:
Sega Genesis
Sega Nomad (if you haven't heard of this, it's basically a hand held genesis!)
Sega Dreamcast
Playstation 1
Original Gameboy
Gamecube with Gameboy Player so i can play all my gameboy games on the big screen
Nintendo DS
Xbox 360
At one point I had all those plus original x-box, ps2, ps3,psp, N64, Wii, original NES, And Super NES
My fav's were the Nomad, Dreamcast, psp, super NES, and XBOX 360.
I spent way too much time on Vid games so I sold everything I had and got back into working out, reading and drawing. But I am playing Plants vs. Zombies on the thee PC. An addictive lil game.
