Famicom, Super Mario Bros., and The Legend of Zelda

As Nintendo released its first home video game console, the Family Computer (rereleased in North America as the Nintendo Entertainment System), Miyamoto made two of the most popular titles for the console and in the history of video games as a whole: Super Mario Bros. (a sequel to Mario Bros.) and The Legend of Zelda (an entirely original title).

In both games, Miyamoto decided to focus more on gameplay than on high scores, unlike many games of the time. Super Mario Bros. largely took a linear approach, with the player traversing the stage by running, jumping, and dodging or defeating enemies. It was a culmination of Miyamoto's gameplay concepts and technical knowledge drawn from his experiences of designing Donkey Kong, Mario Bros, Devil World (1984), the side-scrolling racing game Excitebike (1984), and the 1985 NES port of side-scrolling beat 'em up Kung-Fu Master (1984). This culminated in his concept of a platformer set in an expansive world that would have the player "strategize while scrolling sideways" over long distances, have aboveground and underground levels, and have colorful backgrounds rather than black backgrounds.

By contrast, Miyamoto employed nonlinear gameplay in The Legend of Zelda, forcing the player to think their way through riddles and puzzles. The world was expansive and seemingly endless, offering "an array of choice and depth never seen before in a video game." With The Legend of Zelda, Miyamoto sought to make an in-game world that players would identify with, a "miniature garden that they can put inside their drawer." He drew his inspiration from his experiences as a boy around Kyoto, where he explored nearby fields, woods, and caves; each Zelda game embodies this sense of exploration. "When I was a child," Miyamoto said, "I went hiking and found a lake. It was quite a surprise for me to stumble upon it. When I traveled around the country without a map, trying to find my way, stumbling on amazing things as I went, I realized how it felt to go on an adventure like this." He recreated his memories of becoming lost amid the maze of sliding doors in his family home in Zelda ' s labyrinthine dungeons. In February 1986, Nintendo released it as the launch game for the Nintendo Entertainment System 's new Disk System peripheral.

Miyamoto worked on various other different games for the Nintendo Entertainment System, including Ice Climber and Kid Icarus. He also worked on sequels to both Super Mario Bros and The Legend of Zelda. Super Mario Bros. 2, released only in Japan at the time, reuses gameplay elements from Super Mario Bros., though the game is much more difficult than its predecessor. Nintendo of America disliked Super Mario Bros. 2, which they found to be frustratingly difficult and otherwise little more than a modification of Super Mario Bros. Rather than risk the franchise's popularity, they canceled its stateside release and looked for an alternative. They realized they already had one option in Yume Kojo: Doki Doki Panic (Dream Factory: Heart-Pounding Panic), also designed by Miyamoto. This game was reworked and released as Super Mario Bros. 2 (not to be confused with the Japanese game of the same name) in North America and Europe. The Japanese version of Super Mario Bros. 2 was eventually released in North America as Super Mario Bros.: The Lost Levels.

The successor to The Legend of Zelda, Zelda II: The Adventure of Link, bears little resemblance to the first game in the series. The Adventure of Link features side-scrolling areas within a larger world map rather than the bird's eye view of the previous title. The game incorporates a strategic combat system and more RPG elements, including an experience points (EXP) system, magic spells, and more interaction with non-player characters (NPCs). Link has extra lives; no other game in the series includes this feature. The Adventure of Link plays out in a two-mode dynamic. The overworld, the area where the majority of the action occurs in other The Legend of Zelda games, is still from a top-down perspective, but it now serves as a hub to the other areas. Whenever Link enters a new area such as a town, the game switches to a side-scrolling view. These separate methods of traveling and entering combat are one of many aspects adapted from the role-playing genre. The game was highly successful at the time, and introduced elements such as Link's "magic meter" and the Dark Link character that would become commonplace in future Zelda games, although the role-playing elements such as experience points and the platform-style side-scrolling and multiple lives were never used again in the official series. The game is also looked upon as one of the most difficult games in the Zelda series and 8-bit gaming as a whole. Additionally, The Adventure of Link was one of the first games to combine role-playing video game and platforming elements to a considerable degree.

Soon after, Super Mario Bros. 3 was developed by Nintendo Entertainment Analysis & Development; the game took more than two years to complete. The game offers numerous modifications on the original Super Mario Bros., ranging from costumes with different abilities to new enemies. Bowser's children were designed to be unique in appearance and personality; Miyamoto based the characters on seven of his programmers as a tribute to their work on the game. The Koopalings' names were later altered to mimic names of well-known, Western musicians in the English localization. In a first for the Mario series, the player navigates via two game screens: an overworld map and a level playfield. The overworld map displays an overhead representation of the current world and has several paths leading from the world's entrance to a castle. Moving the on-screen character to a certain tile will allow access to that level's playfield, a linear stage populated with obstacles and enemies. The majority of the game takes place in these levels.
