In the game, players use the GPS capability of a mobile device to locate, capture, battle, and train virtual creatures, which are the Pokemon, who appear on the screen as if they were in the same real-world location as the player.
The game also supports in-app purchases for additional in-game items, which is part of the strategy of Niantic to earn money from the game, like most developers do.
“Pokemon Go” was released to mixed reviews, with critics praising the game’s concept and the incentive to be more active in the real world while criticizing frequent technical issues apparent at launch.
Despite its mixed reviews, the game quickly became a global phenomenon and was one of the most used and profitable mobile apps in the whole of 2016, having been downloaded more than 500 million times worldwide.
It was credited with popularizing location-based and augmented reality technology, promoting physical activity, and helping local businesses grow by way of increased foot traffic.
However, it also attracted controversy for contributing to various accidents, as well as becoming a public nuisance at some locations. Several governments also expressed concerns over the security of the game, with some countries passing legislation to regulate its use by its citizens.
