How popular is Pokemon GO? For an answer, let's check out the data from some market research institutions. The videogame attracted more than 10 million users worldwide within a week of being put online, was searched more times than "Brexit" during that eventful week, and now has more daily active users than Twitter. And its developer Nintendo doubled its share price in two weeks thanks to game.

Some reports even said celebrities were seen playing it, with one saying Justin Bieber, accompanied by six bodyguards, was trying to capture a Pokemon in New York's Central Park.

Many smartphone game addicts confess they cannot understand why Pokemon GO is so popular. Its pictures follow a low-definition instead of high-definition cartoon style and the battle mode of the captured Pokemons is rather old fashioned. In other words, Pokemon GO has not made any improvements in picture quality or 3D modeling, two core elements of modern videogames.
