Studio e.go! was a Japanese eroge company founded in 1998 by Yamamoto Kazue, which produced fantasy games of various genres for computers, including console-style RPG, SRPG, and ADV ("Choose your own adventure"). Since most of their PC games are for a Japanese-only market, Studio e.go are more or less unheard-of in the west, but English patches have been produced by some fans.
Some products were officially translated to Traditional Chinese between 1999 and 2001 and because they were intended to all ages, the H-scenes inside the story were modified or deleted. Taiwan symbio was the official distributor of Chinese versions.
On March 17, 2009, amidst preparations for the company's 10th anniversary celebrations, Yamamoto Kazue announced that she was leaving the company. This announcement was followed by the departure of all of the remaining staff two days later.
Yamamoto Kazue founded a new company Debo no Su Seisakusho. The company uses a fat sparrow named "Debo" as its mascot.
