First game I ever played was Super Mario Bros. on Super Nintendo. Used to love that game, but it's so boring now. ?First handheld game I played was...Uh...I think Pokemon Yellow for GameBoy Color. I was horrible at it at first. Couldn't beat the first gym leader because of Pikachu not affecting his pokemon.
If I can't remember high school, I can't remember my first game... well, it was some army/war game on the NES with a variety of weapons to choose from. I played it for hours on end when I was young...
My first game was Sonic the Hedgehog on Sega Genesis! I absolutely loved it...and I still do. The Genesis will always have a special place in my heart!
