 Many of the features requested are based on real world uses cases of game developers working with PlayFab. This includes Indie titles as well as AAA titles. But don't get me wrong, this project is not a statement of PlayFab being bad for any of these users. This project is supposed to close a gap towards a developer focused audience that is used to CLI based tools and processes. Ultimately this project will enable to get up and running with PlayFab faster and test your games integrations faster and more reliable, even in a CI/CD environment.
