Codex Gamicus

64 Ōzumō (大相撲, 64 Ōzumō lit. 64 Professional Sumo Wrestling) is a sumo wrestling game for the Nintendo 64, and was released only in Japan in 1998. It is generally rated as a relatively bad game; Gamespot gave it for example an 3.9 out of 10. It simulates various aspects that a Sumo wrestler has to go through, like diets and training. The graphics were considered "mediocre at best" and the game itself was entirely in Japanese. Despite the poor reception, the game generated a sequel, 64 Ōzumō 2.
