The Legend of Zelda
The Legend of Zelda is a series of adventure games for the Nintendo system. One of the oldest franchises, alongside Super Mario, at least one game has graced every console Nintendo has put out. With its epic landscapes, focus on puzzles, and wide array of monsters and races, the Zelda series is a goldmine for an enterprising Dungeons & Dragons DM to draw from for inspiration.
Tabletop Games
Officially, there are no Zelda tabletop games. Unofficially, homebrewers have tried their hand at making some. A Legend of Zelda D20 system has been floating around the net for years, and /tg/ has been busily working on a Legend of Zelda RPG. There's also Megaton, which is a wargame set in the Zelda setting.
