I'm playing a game created by Niantic, the startup that was the force behind the 2016 smash hit mobile game Pokemon Go. You know, the game that was the fastest in App Store history to hit $1 billion in revenue and that still ranks among the most played in the world.

Pokemon Go's popularity was rooted in how simple it is: Grab a phone, point it at the real world and on the screen you see the sidewalk in front of you. Then, suddenly, a Pokemon -- or "pocket monster" -- pops out and bounces around. Your job is to capture it by effectively hitting it with a Pokeball. The Pokemon tagline: "Gotta catch 'em all."
