It could be (pretty much) any distro you want – considering scripts like armbian-gaming exists and can give you a “one stop shop” experience.
Why running scripts like these instead of downloading the “real thing”? When you have “obscure”/unsupported sbcs and you need to “make your own” version of it.
Why “we” should bother with that when -you- can do it yourself? Linux is a “free” ““operating system”” (Not absolutely free, but at least way more “free” than Windows) – learn the ways to do that and implement these changes yourself.
