Loads of people still play. The gyms near me often change hands. Though I find I don't open it as much since they introduced Adventure Sync. Now you can hatch eggs and collect candies without actually playing the game. The state and quality of the game is so much more compared to when it first released, though. So many people were playing when it first came out, it was always going to lose lots of players after time, but if it was this padded out with features when it launched, more people would have probably stayed interested.
