Question

Operating Systems

Is it possible to create an operating system for games made with Unity?
Operating system "collection of games" similar to the operating system of the Play Date console
+ the ability to open certain sites.
Is it possible?
If so, how?

Answer 1

Obviously the answer is "yes" (because somehow it works now).
Another issue is that writing one from scratch to support Unity would take a huge amount of time, money and expertise, because in fact, a fair amount of Linux would need to be replicated.
And to assemble from pieces like linux + mono + a beautiful toy store - yes, please, as many such projects as you like, the same SteamOS
In comparison with the playgate console, there is a big difference - there is no special operating system there, there is a primitive gasket between the hardware (also quite primitive) and the code game, which actually does all the work.

Answer 2

Well, in theory, anything can be done. If you have a budget with 8+ zeros, a couple of years, hundreds of smart programmers and agreements with equipment suppliers who decide to create firewood for your axis and, of course, unity developers who agreed to port the engine to your axis (also, of course, for an amount with decent zeros).
