Video game pioneer Trip Hawkins is going mobile. His latest act, a Silicon Valley company called Digital Chocolate, is developing games and “lifestyle” applications for portable phones. He hopes the new venture will turn out like the first he founded, Electronic Arts, the leading video game maker. His most recent gaming company, 3D0, went out of business after a decade. Hawkins spoke with USA TODAY’s Edward C. Baigat last week’s DemoMobile conference in La Jolla, Calif.
