How retro or how old? My earliest console was the NES I bought with my sister when I was still in the single-digits, I played SMB1, SMB2, SMB3, Tom & Jerry, The Simpsons, Dr. Mario, McDonald Land, Snake Rattle 'n Roll (didn't own that one), Duck Hunt (never owned it), I can't remember the other games, but I owned 9 games on before I gave it away.
My earliest gaming experience, however, was on an Amstrad Machine that my older sisters owned, there I played Ghost Busters, some detective game and a winter sports game, etc.
