I thought the same.
But it appears that's just the hand-holding support included price for when your big and need that, I'm guessing. https://heroiclabs.com/nakama-enterprise/
It seems like you can build and run everything yourself with whatever cloud or onprem setup you want.
I still think a free tier would be nice though. It’s not a huge pain in the ass to setup looks like, but still...I bet they’d be more popular if they did.
On the tutorial, I’d advise cutting into sections. Easier to read, you can go more in depth for each section, you get more posts out of it.
Nakama looks really good. Is 600 really the cheapest pricing? What about for just messing around?
