I guess I’m trying to compare the bits and pieces that are the same across these platforms and that’s why I was wondering about developing for things like the steam deck. I agree that providing a development space and tools for development when you are the entity providing the hardware is different than acting as a management and aggregation tool with appropriate included services. I’m still reading this https://partner.steamgames.com/doc/home

And seeing if I can find answers to some of the questions I have about what services they do provide on the development side for the hardware they do sell.
