kid Pokemon Go is an iPhone app that uses the back-facing camera to give the appearance of Pokemon in the real world. Essentially its augmented reality. Such a thing is impossible on a Chromebook because it doesn't have a back-facing camera to give the impression of finding a Pokemon in the real world. Perhaps you could make a Pokemon game, but those already exist for Chromebooks in the form of hundreds of online emulators. Also, even if you did make it, are you seriously gonna walk around waving about your Chromebook in public to find Pokemon?
