The Incredible story of Pokemon Go creation

While it feels as if it appeared from nowhere, Pokémon Go is painstakingly assembled from what came before it: an overnight success 20 years in the making.

“I love the game. I’m running around and playing it a lot. But it’s not like it came out of the blue,” says Dennis Crowley, whose life has been built around location-based games. As a technology graduate student at New York University’s Tisch School of the Arts interactive telecommunications programme in 2004, he built Pac-Manhattan, a real-life version of the Pac-Man arcade game on the streets of Manhattan. From there, he created location-based games including ConQwest and Dodgeball before co-founding Foursquare – a game-type app that lets users check in to locations to earn points and meet friends – in 2009.

Crowley points out that much of the game’s success rests on the longevity of Pokémon itself. Originally a pair of Game Boy games released in Japan by Nintendo in February 1996, in early Pokémon a player travelled through the region of Kanto attempting to capture 150 of the titular creatures and train them to battle the Elite Four and become the champion of the region.

By the time the games hit Europe in 1999, they had extended into comics, cartoons and a trading card game, the last of which was arguably more popular at its peak than the Game Boy games themselves.

Eventually, the Pokémon craze died down, at least in the west, but the series never went away. Pikachu, the “electric mouse” Pokémon that has become the game’s mascot, has remained recognisable worldwide, and the main game series, still one of Nintendo’s top sellers, is entering its seventh generation.

At the same time, a Google subsidiary called Niantic was building its own, much smaller fanbase. Created from the remnants of an acquired mapping firm called Keyhole, which had built what became Google Earth, Niantic’s first major product was Ingress: a location-based social game in which players compete for control of points located at physical landmarks in their neighbourhood while increasing their own power in the conflict by tapping into minor landmarks as they play.

If it sounds familiar, that’s because Pokémon Go is almost totally based on Ingress. Niantic gained independence from Google in August 2015, a move that freed it to seek commercial partners for future projects, and the first one, with the Pokémon Company and Nintendo, was a winner. Crowley points out that the familiarity to millions was key: “I don’t know it would have worked if someone made up characters and called it something crazy.”

The resultant game has been simplified to the point where it can be played and understood by almost anyone, but it has Niantic’s four years of experience behind it.

Which is why it is somewhat strange that Pokémon Go is successful despite – rather than because of – the actual app. “The hardest part of this game is not hurling your phone on the ground when it crashes just as you’re about to catch a very rare Pokémon,” says Sarah Jeong, a writer and lawyer who has been obsessed with the game since its release in the US a week ago. “It also has no explanations for any of the mechanics,” she adds.

It’s true: everything from how to fight in a Pokémon gym, to the specifics of catching Pokémon, to almost the entire user interface is unexplained. But for Jeong, that adds to the joy at the heart of the app – its relationship to the real world.

“The funny thing is that the user unfriendliness just means that players will talk to each other more in physical space when they run into each other – asking for tips and tricks and basic explanations.” Like the kids on my street, it’s hard not to want to talk to other players you meet on the go – a seemingly accidental quirk of the game, but one that helped it go superviral.

Those photos are the other key to Pokémon Go’s phenomenal growth. The feature, known as augmented reality (AR), amplifies the premise of the game: that you can be a Pokémon trainer in real life. When you encounter a Pokémon, rather than simply seeing it standing on a green field, it is instead superimposed on a live image from your camera, bringing the creatures out of the game and into the real world.

The feature has given the game a presence on social networks to match the physical crowds of people who now appear around rare Pokémon with little notice. If you have been on Facebook or Twitter in the past week, doubtless you too will have seen the pictures of Pokémon in homes, workplaces and schools. The Guardian’s editor-in-chief even has one in her office.

Pokémon Go could be the next Draw Something or Trivia Crack: going from unknown to ubiquitous to dead in a month or two. Or it could become more like FarmVille or Clash of Clans, turning its ubiquity into a sustainable long-term fanbase.
