Started gaming around 1994-1995 on the Atari 2600. Still own that same Atari today.
First games I ever played was Pitfall, Mario Bros. and Asteroids.
Acquired a NES a year later, played mostly Legend of Zelda, LoZ The Adventure of Link, Castlevania, Duck Hunt, Metroid, Ninja Gaiden, Super Mario Bros 1 & 2, and Fester's Quest. A bunch others, but those are the ones I remember the most.
Also owned a Game Boy.
In 1997, I got the N64 and that console is most definitely the one that made me into the gamer I am today. I could go on and on about all the games on the N64 that I enjoyed and loved. But my top favorites are Perfect Dark, Golden Eye, Hexen, Duke Nukem 3D, Super Mario 64, Mario Kart 64, Turok 1 & 2, Super Smash Bros. and Conker's Bad Furday.
GameBoy Color was revolutionary for me tbh. I was like holy shit and I loved it. Pokemon Blue & Silver, Army Men 1 & 2, All LoZ for the BGC.
GBA later on, and I thought the GBC was god tier. Pokemon Shappire, all LoZ games for the GBA, Ace Combat Advance, GTA Advance few others I can't think of atm.
PS2 and GameCube were really excellent console favorites of mine, but ofc they can never compare to the N64 for me honestly. Favorites are Zelda and the Wind Waker, Star Wars Battlefront 2, Metal Gear Soild, GTA San Andreas, Need for Speed Hot Pursuit, Super Smash Bros. Melee, Bomberman Generation, Call of Duty Big Red One, Spyro A New Beginning, LotR The Two Towers, Mario Party 4, 5, and 6.
Never owned an original xbox actually but a friend of mine had one and I use to go over there all the time and play it. Loved a number of games on it including Fable The Lost Chapters, Painkiller Hell Wars, Soul Calibur II, Star Wars Jedi Knight Academy, few others.
Got a 360 few years later, not going to go through games I've played on it since it's still a relatively new console for me honestly. Owned a PS3 for a while, but mostly got it for MGS and God of War, as well as other PS3 only games.
Switched to PC gaming about 2 years ago. I still enjoy consoles but now I'm a PC gamer at heart. But nothing will still ever be able to compare or beat the N64.
