Sometime around 7-8th grade (so 11-13) when I got my DS and played Phantom Hourglass. I'm relatively new to the series when compared with others who played when they were younger.
8th birthday got a Wii and TP right after the launch. I beat TP when i was 11! Took me a while and i played and beat OoT, MM, and WW while i was stcuk on TP. Now i have played Every zelda! ^^
I was four when I played my first Zelda, Ocarina of Time. My brother had the Collectors edition, so if your wondering, yes, I did have a good childhood. Zelda filled and all .
the first game i played was the original legend of zelda , but only a little bit of the game when i was about 6. the first game i actually completed was tp late december 2011.
