Street fighter.
Met a guy who loved fighting games and I challenged him on SF2. I played Ryu, he mained Gief. Not only did I lose, one round he got a perfect.
He humbled me, and told me about the FGC. The rest as they say, is history.
Starwing Competition cart and custom console.
Used to have a pixel NES cart with a Super FX label. Decided to change it for the new place, but keep the spirit.
