>Anti-competition bodies are designed to regulate more than just utilities.

I was looking for a better word than "utility" but couldn't think of one. What I mean is that games are unimportant. Grain is a "utility" for me as are computers ect. And I don't think it matters what Anti-competition bodies are "designed" to regulated as I am already giving my own opinion on what I think they should do so for me this isn't a such an important point.

>even though they would be controlling the operating system developed on and targetted to...

That is the issue exactly, which was my whole point. It's an issue irrespective of whether they have 1% or 99% of the video game market. They are the hardware/syscall railraod by which developers ship their software oil. But large marketshare alone is not an issue, and can be assured to be a non issue with something like the Open App Markets Act whereas in something like grain or computers it is almost impossible to show whether a dominant company has used their monopoly to hurt competition. If we just give some basic rules as to allowing users to decide how to use their computers we won't need to care about how large any video game company is.
