Nobody in my immediate family plays Zelda. It's quite sad, actually. My extended family on my step-mom's side, however, is full of Nintendo Gamers. My stepbrother and stepsisters are even bigger Nintendo nerds than I am! I love it when they visit because it actually means I have people I can play Smash and Mario Kart with (aside from online). Other than them, though, nobody in my family is interested in Zelda or Nintendo.
At my university, though, I have several friends who are Nintendo fanboys.
