Just putting a theory out there that Pokémon will not last as the top game longer than Sept 1st 2016.
- Most adults will get tire of the game since they never grew up with it.
- Once you have tried to walk most of the city you are living and working in, there is no more things to collect.
- The gyms will be occupied by the most avid fans can will be over taken.
- Most games will not pay the extra $$ to buy back packs to store more virtual poke balls, raspberries so their game play with plateau.
Like all games, this one shall pass. However Pokémon Go will inspire a new genre of games based on location.
