What Is It?
Pokémon GO is an AR game, meaning that it uses real world settings and adds in a fantasy layer on top of that. That fantasy layer is, of course, the insanely popular Nintendo franchise that launched on the original Game Boy in 1996 and gave the popular primitive portable a second renaissance. In this enhanced take of Pokémon, players travel the world capturing a variety of cute and charming monsters inside Pokeballs, raise their stats, and battle them against each other on a smartphone.
By 'travel the world' here, it is to be taken literally. You need to move around to succeed in Pokémon GO, visiting locations to catch monsters, get items, and more.
