I have not played it but they are all Ponzis
Mostly because bots are trivially easy to make and AI makes it even easier.
The key is a reputation system that can exponentially mitigate botting (doesn't exist).
Hive is the only network even capable of building a rep system like this.
The only ones that aren't Ponzis are the FPS games where you can't buy an advantage.
And they only use crypto for the skins and stuff.
But I don't like first person shooters.
