sadly, my very first memory is of me and my sisters playing atari. I couldn't tell you what game as I was too young, but I remember we had breakout, for sure.
from there we got the NES and I vaguely remember playing Burger Time, Mario 1 and Duck Hunt, and A Boy and His Blob. after that it was SNES, and I actually clearly remember opening the SNES and being upset that it was a family console and not a console for just me.
so basically, I've been into gaming since I was born. I've played since the very beginning and can't mark down a single point in time when I "started" gaming, so to speak. there's not even a point I can mark as when I started to get seriously dedicated to gaming. I'm 22 and I remember playing Mega Man X for hours and hours on end with my cousins on weekends. I would've been 7 or 8, I think? and I was already spending entire weekends devoted to games.
