I dabbled on my older sister's NES and it was some Dracula game iirc, but didn't play it much. It wasn't until I played Kirby for the NES and let me tell you what an accomplishment that was. It took me several tries to beat the final boss, but when I did I yelled it through the house lol. After that I was hooked for LOFE!
I have to add that Diablo 2 on launch and Halo 3 took up a few year of my life because I didn't care about any other game...now it's MK
Edit: Zelda OoT, Majora's Mask, and Starfox was my shit back in the day. I enjoy watching the speed runs for Zelda on twitch.
