Following in the footsteps of John Madden and Tiger Woods, Olympic gold medalist Michael Phelps wants to start his own video game empire. But curiously enough, swimming might not be the main event. "Swimming will be a part of it, but it won't be set in an Olympic pool going back and forth," said Adam Kline, president of 505 Games, the company releasing the series. "This is a pure action game," he added. Does that mean our local aquatic hero could be roughing up bad guys and saving the world? Or will he be running amok a la Grand Theft Auto? The folks at 505 are still toying with a few different ideas and can't comment just yet. More details will emerge closer to the first installment's planned release in spring 2010. The game should be available on consoles and the iPhone. But the lack of specifics hasn't stopped video game experts from speculating.
