For me it was a combination of things. I owned a Gamecube and later purchased the gameboy player and fell in love with Metroid Prime which turned into a love for the Metroid series. I also developed a love for Fire Emblem, Advance Wars, and Smash Bros. before I knew what happened, I was a Nintendo fan. This led me to purchase a Wii and a NDS.
You took me back to the original gameboy that I coveted with the green screen...super mario land was the BOMB!
