Well I have older brothers, so I was born into a house that already had gaming systems. First system I purchased myself was my 3DS. And I think the first game I bought myself was Harvest Moon: Another Wonderful Life for the Gamecube, but I can't be sure.
I mostly played the SNES, N64 and GameCube as a kid.
My first was the original Xbox and I remember the first game I played on it was Crash Bandicoot: The Wrath of Cortex. I still have the original xbox and I'm debating to buy that game again (gave my copy away yeeearsss ago)
My first console was the N64, which was a hand me down from my cousins. Before that, I would borrow my brother's Gameboy but I never had my own so that doesn't count
First system I ever played was the Sega Genesis and probably Sonic the Hedgehog (2?). System I got to own was probably a Gameboy Color with a 32-in-1 cartridge my grandmother brought back from Taiwan.
My first gaming system was a Sega Genesis, which my family owned.
I don't remember my first game, but the Sega Genesis had Sonic, Sonic 2, Disney's Aladdin, Ms. Pac Man and Barney.
My first gaming system that I bought for myself was a New 3DS XL, which I bought in January 2017. My first game on New 3DS XL was Pokemon Sun.
