A game that has you walking around the physical world to find and catch Pokémon, improve and evolve them, and participate in asynchronous multiplayer battles to take control of Pokémon Gyms in real-world locations. A lot of the depth and draw comes from the real-world social interactions that emerge from multiple players in the same physical area. The dynamics of coordinating community members to defend gyms and the opportunity to meet people via a shared activity are far more interesting than the relatively shallow gameplay. As such, the game may have been at its most appealing in the months after its launch when it was pretty common to run into groups of players.
