Integrating GPS with gaming, how cool! Just launched this week, the GPS Receiver for Sony PSP is supposedly only available in Japan.

The GPS receiver currently works with the following titles: Minna no Golf-jou, Metal Gear Solid: Portable Ops, Planetarium Creator Ohira Takayuki Kanshuu: Home Start Portable, and Navigation Soft.
