Ingress as an augmented reality game - discussion

Ingress is an augmented reality massively multiplayer online role playing GPS-dependent game created by Niantic Labs, a startup within Google. The game was originally exclusively for Android devices, and was made available for Apple's iOS on July 14, 2014. The game has a complex science fiction back story with a continuous open narrative.

The gameplay consists of establishing "portals" at places of cultural significance, such as public art, landmarks, monuments, etc., and linking them to create virtual triangular "control fields" over geographical areas. Progress in the game is measured by the number of "mind units" (MUs) captured via such control fields, i.e. people nominally controlled by each faction (as illustrated on the Intel Map). The necessary links between portals may range from meters to kilometers or hundreds of kilometers in operations of considerable logistical complexity. International links and fields are not uncommon, as Ingress has attracted an enthusiastic following in cities worldwide amongst both young and old. More: en.wikipedia.org.
