GREE is setting up shop in San Francisco in order to facilitate the launch of its global platform during Q4 this year. The Japanese network operator, and social and mobile game developer, plans to use the time before launch to build relationships with local developers and publishers. Titles are to be offered through the firm’s existing service, along with that of OpenFeint – its most recent acquisition – and the first two will go live next month. It’s Japanese service boasts 190 million registered users, and it expects to its fiscal year-end sale to reach $2.1-$2.5 billion. Currently, the service offers over 7,500 games from more than 20,000 partners, and has its own internal development studio. Other offices for the firm are located in Beijing, Dubai, London, Sao Paulo, and Seoul. Thanks, Gamasutra.
