Actually, I'm kind of disappointed with Pokémon GO.
I've been played Ingress, game that developed by Niantic too, earlier than Pokémon GO, since 2 years ago and that was amazing. I mean I must go outside to play it, got to meet people to farm, and make a huge operation between towns. I made pile and piles of friends from that game. Although it wreck my life, but I love the experience.
...but, Pokémon GO somewhat slipped from my expectations.
There is no communication system on the game. When you play Pokémon GO, you don't really need to meet new people. You can thrive on your own.
You meet new people just because there are so many people play it.
...and if you amaze how sometimes Pokéstop has weird name. It's because basically Niantic use Ingress's portal to make those Pokéstop and we Ingress players are trying turn literally everything into portals.
