The company, which employed just under 300 individuals before its closure, was founded on July 1, 2003 by Yoshiki Okamoto after his departure from Capcom.

He then moved to Capcom, where he worked on many renowned video games; he worked on the Resident Evil series and helped produce Street Fighter II.

While Game Republic was a completely independent developer able to produce titles for any publisher and/or platform they desire, during the company's early years it had enjoyed a close relationship with Sony Computer Entertainment, with many of their early titles funded by and produced in conjunction with the publisher.

In June 2011 reports surfaced of Game Republic shutting down its website and vacating its offices.
