Just like Ingress, Pokemon Go requires the player to be in the streets to play the game. Most of the Ingress portals have then been reused as either a Gym or a stop. The stops allow the player to collect whereas the Gym is owned by one of 3 opposing sides and needs competing for. Monsters can be deployed to own the Gym and battles ensue to claim it from them. If a player’s own side already owns the Gym then they can battle anyway and upgrade it.
The screenshot above shows a real world object of a statue, and then a creature imposed on top using Augmented Reality. The player interacts with the screen to throw balls and catch monsters.
This game has proved hugely popular with younger people because their screen shows monsters in the area which can be clicked on and caught. The summer of 2017 saw a huge rise in the number of young people on the streets, and my local town had benches full of teenagers sitting outside churches on sunny days.

Pokemon Go lacks the strategy and co-operation between players that Ingress possesses. For this reason it has waned in popularity amongst Ingress players that moved over, and amongst the younger population that have now ‘played it’ and have little left in the game to complete.
