Niantic's first game, Ingress, is quite similar. Run around in the real world, GPS on, game constantly updating Google/Niantic's servers about where you are. Niantic is a Google enterprise, btw., and here's the kicker: once you're hooked on the game and you are about to level up to level 3 (maybe 15 hours of playing or so), you are required to "verify" your account to be able to continue playing, by giving Google your phone number to get a "confirmation SMS", effectively linking your real person to all past and future movement data of where you have been, at what times, during what days. How's that for creepy and treacherous? If this isn't the equivalent of having a GPS tracker on your person, I don't know what is. Boycott that shit. Surely Pokemon Go is the exact same stuff? Just one step further, with your phone letting "them" see what you see, in addition to engaging a shitload of more people to keep track on.
