Sony Ericsson is working with third-party tool developers to create tailored games for its Xperia Play smartphone. The Android 2.3-based Xperia Play comes with a 4-inch touchscreen and slide-out PlayStation controls. The company is attending the Game Developers Conference in San Francisco to show off the phone. More than 50 gaming titles will be available when the Xperia Play launches in March, company says. The hard part will be to educate users, so they don’t expect all premium games will be free or cost around US$0.99.”]
