I vaguely recall getting about 30 days out of the free tier until I decided to start purchasing base/expansions.
So, I think I’d just say be aware that it’s probably not an “indefinitely free” kind of thing – but will give you a sufficient amount of entertainment until you want to consider if you want more.
These Community Camps are special spots that have extra PokeStops and Gyms. But what’s the catch? Well, they are designed to bring local players together.
The feature is part of the Community Ambassador Program, which means there will only be certain players who can create these Campsites. You must apply and eventually get accepted as an Ambassador. There are perks for those who are accepted, you get stuff like free items and support from the game’s team. However, some of the players are saying that it’s hard to get approved, and they are still on the waiting list.
Some trainers seem to be happy with it, they think it would help in making the game more social. While some aren’t really excited for it, they think the developers are trying to “force them to be extroverts.”
