After a year in beta, Ingress opens fully to the public tomorrowafter events in 14 cities that are serving as a kind of season finale. Ingress can easily be seen as a lark for Google, which launched the game through its Niantic Labs internal incubator. Encouraged by the support it has seen from players — more than 1 million people have downloaded the game, and player communities have sprung up around the globe — Niantic is starting to think more deeply about how Ingress can be turned into a platform that anyone can use to build an alternate reality game of their own. An open real-world gaming platform has been Ingress goal from the beginning, says John Hanke, who helped create Google Earth and led the companys location services before launching Niantic as an internal incubator within Google.
