Nope. My mom isn't really the video game playing type. Unless of course you count Tetris. She sure does love Tetris, she used to play it all the time, although, lately, I haven't seen her play it at all. Then again, I don't live with my mom, but still, I haven't seen her play it at all when I do see her. But I'm getting off topic here, so I'll just stop haha.
As for my dad, he's the kind of person who plays games like Call of Duty, and really nothing else, so I'd say there's no hope for him haha. My brother has only played Ocarina of Time, and refuses to play anything else, so once again, no chance.
No one in my immediate family, meaning siblings and parents, is really a zelda fan other than me, and even I am not a HUGE zelda fan. I mean, I've played all the games, talk about them, and am on a "ZeldaDungeon" forum but.... you know, I guess I kind of am a big Zelda fan haha.
The other family like person I can think of who plays Zelda, and knows about it, is my mom's boyfriend. He REALLY likes Zelda 1 and Wind Waker, he's beaten both a lot of times. He also tries to play Zelda II a lot, but, since he isn't a super human, he isn't super good at it, and can't beat it. When he was a kid he did beat it however, but not anymore.
