CryptoKitties, Decentraland, God's Unchained etc. Is it possible to earn profit on this games or not?
I think it's possible. Because now all fields can be applied on the blockchain system. It only depends on how the development they make, whether it can be profitable or even detrimental. In the past there was also a gaming platform that had almost the same concept, and was good until now, and was still used by them.
