Anyone who spends any amount of time around me knows that I've taken quite a shine to Pokémon Go. I've been playing since last July, and just today managed to collect all but the location-locked Pokémon from Asia, Europe, and Australia (
/me glares at Snook), and Igglypuff.
One of my frustrations with the game was that you had to be walking with a vector greater than zero in order for the game to register movement. Which is to say, walking on a treadmill wouldn't work, because the movement was tracked only through GPS. You don't move according to GPS when you are walking on a treadmill.
