do you have a resource (blog, youtube video, etc) where one can get a quick overview of Pokemon Go? When I played it there was not much you could do, so I dropped it completely. I may still have the app installed though.
I'll list some sites below. Though the new main focus of the game is "raids". When you open the game you'll encounter gyms at various locations. 2-3 times a day a gym will have a Raid Boss (you'll know a Raid Boss when you see it, because you have to use a raid pass to fight it - you get 1 pass a day, though you can get more by using coins, which you get by taking and staying in gyms, or by paying for them). The boss will be rated from 1 to 5 stars (1 being easy - a single player can take it down; 5 being the hardest, requiring several players, though defeating a level 5 Raid will earn you the possibility of catching a legendary Pokemon).
The hardest part of the game is getting enough players to take down a high level boss, which is why people have taken to joining chats to coordinate raids. Though this may be different for highly populated areas, and it's still possible to just randomly show up at a raid and find people waiting for it to start.
