Microsoft this evening set out to make Windows Phone 7 a higher-end game experience by detailing some of the first 50 launch titles. Its smartphone OS will trade on major game names but will sometimes use them as companions that tie into full Xbox games. Crackdown 2: Project Sunburst will be a full game acting as a side story; Halo: Waypoint will tie into the universe, but will primarily be used for community and video viewing.
