Maybe research instead of those blockchain games outside Bitcoin. There are lots of it and almost on a hype right now.
Yes. I've been searching for such games to no avail. We could say that Bitcoin-based games are extinct because of the high fees and slow transaction processing times. There's hope with the Lightning Network, though. But not everyone use it these days. Altcoins like Ethereum and Bitcoin Cash are more suitable for micropayments than Bitcoin itself. The real problem would be getting game developers to make a game that would pay fractions of a cryptocurrency.
Despite crypto/Blockchain tech's success, the industry lacks behind prominent game developers and game companies that will help it reach a wider audience in the mainstream world. Gambling games are the only ones that are still paying Bitcoin. I hope new games take advantage of the Lightning Network to increase mainstream adoption of Bitcoin worldwide.
