According to my father, when I was very very young at age of 2 (I barely remember obviously). My uncle used to buy Nintendo consoles at launch dates, and around that time the SNES was The Super Power Console™. Because they wanted to see my reaction to videogames, they put the controller in my hands with Final Fantasy 3 (best known as VI) and seriously, I just can't with what they did expect from a toddler without any abilty to read whatsoever trying to play an RPG game. That explanation came one day I was playing that same game (but now at the age of 25) on my 3DS on a family trip, and I said "Why is this intro music giving me such a nostalgic feeling, is the first time I play this game" then my father and uncle explained me what I have already said, so maybe deep in my memory, the intro music from the game got really stuck.
In case this doesn't count as my first played videogame, then that would be Super Mario Bros 3 at the age of 5, I used to play it as heck as I didn't had any other videogame available until I became self aware that other games existed (at the age of 6), so I started to ask for games as christmas gifts.
