Entergram

Entergram, Inc. is a publisher and developer based in Osaka, Japan. The company was established in 1999 as NSP Engineering (エヌ・エス・ピイエンジニアリング), a wholly-owned subsidiary of TGL. The company would be renamed TGL Planning Inc. (株式会社テイジイエル企画, TGL Kikaku) in November 2002, and all game software development and publishing operations were transferred from TGL to TGL Planning the following year, including the GIGA adult games brand. The company was again renamed to Entergram in April 2016. Prekano was launched in 2017 as a budget adult games brand. Entergram announced in March 2023 that it was discontinuing the GIGA and Prekano brands and leaving the EOCS (Ethics Organization of Computer Software, an industry organization of adult game companies), effectively ending production of original adult titles at the company. Future releases would be either original non-adult games, or conversions of adult titles adapted for console release.
