ClayFighter 63 1/3 is a 1997 fighting game for the Nintendo 64 that distinguishes itself with a unique claymation-inspired visual style. The game features a tournament-style roster of clay characters, including Bad Mr. Frosty, Bloopy, Bonker, Clayboy, and Constance, all drawn from the ClayFighter universe. Players select from this eclectic cast and battle through a series of opponents in a fighting tournament format reminiscent of the clay comparator toys popular in the 1960s. The game's title itself is a running joke - the '63 1/3' portion was earned as a self-deprecating nod to its mediocre quality, evidenced by its low IGN score despite being an otherwise amusing and entertaining experience. While the game is often praised for its charm, goofiness, and fun gameplay, critics panned its technical execution. It is frequently cited as one of the more entertaining Nintendo 64 titles despite its weaknesses, particularly notable given the console's relatively short lifespan. An improved edition called ClayFighter: Sculptor's Cut was released in 1998 as a rental-only mark for the N64, featuring enhancements over the original release.
