I was five. I remember it like it was yesterday. I slept over at my cousin's house for like a week because my parents left the country to attend a funeral. I remember playing a bunch of games on my cousin's many systems.
I played Donkey Kong Country on his SNES, some Power Rangers side scroller, also on his SNES, an awesome snowboarding game that in retrospect had to be 1080 Snowboarding for the N64 even though something nagging me is making me think it was really a PSX game, and Ocarina of Time. I remember being super scared at night when creatures would come up from the ground to attack you, and I remember watching my cousin beat the game, escaping Ganondorf's collapsing tower while Zelda opened doors.
Absolutely fell in love with video games at that moment, so much so that I was depressed when I finally had to leave. Little did I know that waiting for me when I went home was an N64 with Super Mario 64 and Diddy Kong Racing, as well as an NES with what had to be 50+ games, including Super Mario Bros. 1,2, and 3, Mega Man IV, Mach Rider, Elevator Madness, TNMT, Excitebike, Duck Hunt, Bomber Man, and the original Legend of Zelda.
Suffice to say, it was no competition; my NES got more love. It was the greatest parenting moment my parents ever had weening me on what made Nintendo what it is today. It's a great treasure being able to see gaming evolve the way people much older than me did, and when I have a kid, his first system will be an NES too.
