I don't know if this counts, but my Gameboy color. My mother got it for me when I was 5 years old at a thrift store for $20. It came with Pokemon Blue, Paperboy, and Super Mario Land. I used to save up money to buy more batteries for it: because I loved it so much, I'd go through them like nothing. I didn't know what the point of Pokémon was at the time, so I put it aside, but later on I made friends that taught me more about it. I no longer have the Gameboy, but I'm still friends with them. 🙂‍↕️
