Some analysts say that Nintendo's days are numbered. Holiday sales of its new console, the Wii U, have been lackluster compared to Microsoft's Xbox One and Sony's PlayStation 4.
But since Nintendo still offers some of the most popular game franchises, the love of Zelda and Mario may keep the company going for a long time.
In preparation for this story, I put out a call to talk to die-hard Nintendo fans. I was inundated with responses. Among them, Brian White, 30, grew up playing the Zelda games.
Now he's got a daughter. "We named her Zelda," he says.
White says as a dad he's happy Nintendo games aren't filled with violence.
"It's something I can play and have my daughter sit in front of the TV and not be ashamed of and wonder how corrupt she's gonna be," he says.
Zelda is a series of fantasy adventure games where the main character, Link, has to save Princess Zelda and the world. The soundtrack is so beloved that it's been performed as a four movement symphony.
Manny Contreras, 25, has seen the symphony performed twice. He says the music reminds him of great experiences he's had playing Zelda. "It's great music just in general. Even if you're not a fan, if you listen to it, you're probably surprised by just how good it is."
Love of these long-time franchises is the main reason that game analyst P.J. McNealy thinks that predictions of Nintendo's demise are overblown.
“ If you look at video game sales over the last 20 to 25 even 30 years and look at the top 10 games that have sold, Nintendo's probably owned five, six, seven, eight of those games on those lists.
