Sigma Enterprises, Inc., aka Sigma Shoji Co., Ltd. (シグマ商事株式会社) was a Japanese game publisher.
Sigma Enterprises operated as a Japanese game publisher and developer from 1980 until 1992. The company released ten games that appear on PlayPile, with eight titles listed under their publishing credits and six showing them as developers. Their catalog is heavily weighted toward the arcade market, which accounts for six of their releases. They also targeted the Family Computer with three games and the Super Famicom with one. The shooter genre dominates their output with six entries. This is followed by four arcade titles that do not fit a single sub-genre label in your data, two adventure games, two platformers, two role-playing games, and a single fighting game. Their activity was most intense during the 1980s when they produced seven games. Output slowed considerably in the 1990s with only three releases before the company stopped operating in 1992. Recent entries from their library include Maka Maka released in April 1992 and Time Zone in October 1991. Fuzzical Fighter arrived in June 1991, while Hissatsu Dojo Yaburi came out in August 1989. Their earliest listed title is Akazukin from February 1984. The IGDB bio notes that Sigma Enterprises was also known as Sigma Shoji Co., Ltd. The company had a very small footprint overall with only ten games total over twelve years. Most of their work focused on arcade shooters, suggesting a narrow design philosophy. They did attempt to branch out into other genres like adventure and role-playing, but these titles represented only a fraction of their catalog. There is no data provided regarding critical scores or user ratings for these specific titles, so the quality of their games remains unknown based on this source alone. Their output volume was low compared to major publishers of that era, and they ceased all activity shortly after their last release in 1992.
