Today is a huge day in the world of video games. Nintendo releases its latest system the Switch, along with a new game in the Legend of Zelda series, Breath of the Wild, an incredibly ambitious game that took developers years to make. Here are some more fun facts about the world of Zelda.

• Game creator Shigeru Miyamoto wanted the princess character central to the game to be “mysterious” and “unattainable.” So, he took inspiration from Jazz Age author Zelda Fitzgerald…and went ahead and named the princess Zelda as well. (And Robin Williams was such a big fan of The Legend of Zelda that he named his daughter Zelda.)

• Miyamoto was inspired to create the game of magical woodlands and spooky dungeons not from fantasy fiction like Lord of the Rings, but his own childhood adventures. He grew up in a small town outside Kyoto, Japan, and he’d spend his time wandering around the forests. One time he came across a deep hole in the ground, and he had a lantern with him and started exploring…and found a cave system.

• Other games in the series have a bit more surprising inspiration. The 1993 game Link’s Awakening for the Nintendo Game Boy was developed because of another early 1990s pop culture sensation: Twin Peaks, David Lynch’s ABC series about a murder in a tiny and surreal Washington town. In Link’s Awakening, Link meets several very strange characters who all live in a bizarre little town. The game’s creator, Takashi Tezuka admits that “at the time, Twin Peaks was rather popular. The drama was all about a small number of characters in a small town.”

• Link, the questing warrior at the center of the Zelda adventures has been left-handed for most of his 30-year history in games. That changed when Nintendo started making games for the Wii console. Because that system is powered by users holding a wireless, motion-sensing remote joystick in their hand, Link became right-handed so his onscreen movements would match those of the players—of whom are overwhelmingly right handed.

• A Legend of Zelda game was one of the first ever online-only video games…way back in 1995. Nintendo users in Japan could buy a device called a Satellaview that allowed them to connect to the Internet (via a satellite network) and play games. Among the first offered was BS The Legend of Zelda. (Don’t worry—the “BS” means “broadcast satellite.”) Unlike today’s world in which games can be played online whenever players like, BS The Legend of Zelda was available for a certain time each day, like a TV show, and was only playable at that time. (This system of game delivery ultimately flopped.)
