When Phil Spencer was appointed the new head of Xbox following the departure of longtime lead Marc Whitten, he promised a re-focus on gaming across all Microsoft platforms. That wasnt a huge surprise, of course –most folks know Spencer as the Microsoft Studios guy; the guy who makes game deals; the guy who speaks at E3 about games during Microsofts keynote. While thats all accurate, Spencer is also a longtime Microsoft employee, starting as a programmer and working his way up.
