When I first played games, my family already had: Atari 7800, NES, SNES, Sega Genesis, TurboGrafx-16/Turbo Express, and Sega Game gear. I played all of those and can't remember which would have been my actual first one.

I think the first system bought after I started playing stuff was the PS1. First system I bought with my own money was a Gamecube.
