I build the biggest Pokemon Go community in Belgium within 2 months, started 1 week before it launched ( to test Facebook ads), a long time ago by now. I'd say Facebook ads is too expensive for a not hyped term ( we had / 10 the normal costs because of the hype). Some giveaways grew it together with a lot! of content ( advertised) planned out ( i usually checked Sunday for content for the next week). Starting earlier than others on fb was a pro too. Finding good/interesting content was relatively easy. It's not easy, cheap and very time consuming though. A like doesn't mean they would join an event ( we had about 100-200 participants for events with entrance tickets for theme parks)
