―Official description

Fix-It Felix Jr. is one of the games of Litwak’s Arcade in Disney’s 2012 animated feature film, Wreck-It Ralph and its 2018 sequel. It is an 8-bit platformer starring the titular hero, Fix-It Felix Jr., who must save an apartment building from being destroyed by his rampaging rival, Wreck-It Ralph. The game takes place in Niceland, a quaint town inhabited by numerous, pint-sized NPCs called the Nicelanders.

Developed by the fictional Japanese company, Tobikomi, Fix-It Felix Jr. is one of the oldest games in Litwak’s, as the cabinet began operating back in 1982 (thirty years prior to 2012). Niceland is mainly a single tall apartment building with a forest surrounding it and a dump nearby. It also has scenic lakes, a starry sky with multi-colored stars, and is eternally set at nighttime.
