Fix-It Felix, Jr.: The game is largely based on the original Donkey Kong. Both villains, Ralph and Donkey Kong, are large and angry characters who stand atop a building structure and toss objects down at the hero. Both heroes, Fix-It Felix and Jump Man (aka Mario), are handyman characters who climb up and around the building to eventually reach the top and watch the villain fall off the tower. The game's name is also a reference to Donkey Kong Jr. There is a slight reference to Rampage, a game in which the player controls kaiju-style monsters (including one representing King Kong and another one named Ralph). In this game, the monsters climb the side of the building, punch open the windows, and grab the residents inside. Ralph is seen doing this at the beginning of the movie when the game is first seen. The game's building, opening/shutting windows, and the fact that Fix-It Felix scales the front of it also all somewhat resemble Crazy Climber from the early 1980s.
Hero's Duty: Inspired by various futuristic armored soldier games such as Doom, Quake, Halo, Mass Effect, etc. The Cy-Bugs are inspired by the Metoroido and Aliens franchises and could be seen as an homage to movies like Starship Troopers, which also had games made based on the property. The name is a reference to popular first-person shooter franchise Call of Duty.
Sugar Rush: Inspired by cartoonish kart racing games like the Mario Kart series, Diddy Kong Racing, and Sonic & Sega All-Stars Racing with cute characters, power-ups for offense and defense, boosts, obstacles, and various weather conditions. The game's design is based on the board game Candy Land.
Turbotime: The game is inspired by Namco's Rally-X; the colors and designs match almost perfectly. Turbo himself greatly resembles Rally-X's unnamed protagonist.
