So, I'm going to be "that person" and insist that my very first gaming system was my parent's computer. I was playing Might & Magic when I was really little. Granted, I was playing it badly, but I was having fun with it.
As far as consoles and handhelds go, my first one was a Gameboy Color with a Barbie game. I played that game for hours. My second game was Pokemon Yellow.
Nintendo 64
I remember always playing DK64, And when I turned 9 I played Conker with my brother at like 12AM so we wouldn't get caught by my mom
Dad was coo with it tho
First console I've both played and owned was the Super Nintendo Entertainment System, along with Yoshi's Island and Mario Paint. My former gamer mom bought this for my sister, but the latter didn't appreciated it that much. I then played more regularly than them, and exceeded their skill quite easily, despite struggling on certain parts. As the time passed, we got Donkey Kong Country, Mega Man X2, Super Troll Islands, Super Mario World, Justice League: Task Force and rented a lot of SNES games. Shame I sold it around early 00s.
The first ever game console I played on was the Gamecube when I was about 4/5 years old, and the first game I ever played was in fact Animal Crossing... Or it might have been Super Mario Sunshine, but either way, both were really awesome.
The first ever gaming system I owned, though, was a Gameboy Advance on my 6th birthday. :3 I loved it to bits and I have always loved playing games. I remember I used to play Harvest Moon all the time on it, because I loved the Gamecube version loads too.
My first own console was a turquoise Game Boy Color, which was funny as I didn't even have any games for it for like 3 months. I like liked to turn it on and pretend I was playing something (yeah I did that a LOT while waiting for my first game for it).
We also had NES and SNES before but they weren't mine, they were my dad's.
The first console that I had was a Sega Genesis, which we got back when I was 3 or so. I still remember spending hours on end playing Sonic 2, and to this day it's still my favorite game.
