This is the story about the ten levels John Hanke had to achieve in his life in order to create Pokémon Go.

Here are the first four levels:

1st Level up: In 1996, while still a student, John co-created the very first MMO (massively multiplayer online game) called ‘Meridian 59’. He sold the game to 3DO to move on to a bigger passion: mapping the world.

2nd Level up: In 2000, John launched ‘Keyhole’ to come up with a way to link maps with aerial photography, and create the first online, GPS-linked 3D aerial map of the world.

3rd Level up: In 2004, Google bought Keyhole and with John’s help, turned Keyhole into what is now ‘Google Earth’. That’s when John decided to focus at creating GPS-based games.

4th Level up: John ran the Google Geo team from 2004 to 2010, creating Google Maps and Google Street View. During this time, he collected the team that would later create Pokémon Go.

Read the rest. Interesting to watch this all unfold.
