Video game researcher Patrick Kellogg posited that Cube Quest was likely the inspiration for Polybius, an urban legend in which US government operatives create a Tempest-esque shoot-em-up of the same name that has lasting psychoactive effects on those who play it. In Kellogg's analysis, he notes that Cube Quest features similar Tempest-style gameplay and sports vibrant, surreal backgrounds like the kind described in the urban legend. The backgrounds in Cube Quest were reproduced by running a LaserDisc player installed in the game's cabinet; because LaserDisc technology is much less reliable than solid state media, the cabinet required constant maintenance from technicians, which Kellogg cited as the likely inspiration for the government agents who periodically harvest data from Polybius in the urban legend.
