Are you expecting to run Windows 11 ARM version on your Mac Mini directly, or within Parallels?
Apple Silicon has no UEFI support except as provided by Asahi, so that would be needed at a minimum to boot Windows 11 natively. Then there's the whole issue of having native Windows drivers for the Apple Silicon-specific hardware.
You’d run FEX with WINE/Proton, no windows needed. If you did use a VM, I’d think it would be a Linux VM. But, Linux VM on macOS could already use Apple’s Rosetta2 for x86_64-to-arm64 translation.
Speaking of which, maybe you could just run the games with Apple’s WINE “game porting toolkit” direct with Rosetta2. Worth a Google.
EDIT: indeed, you can already play x86 windows games on Mac using software written by Apple: https://gist.github.com/Frityet/448a945690bd7c8cff5fef49daae...
I think they're wishing for something like the Proton/Fex combination for running x86 Windows games on ARM Macs, like they already do for Linux.
I think it's a pretty reasonable wish for more macOS + Apple Silicon support of games, including more native FEX & Proton ARM support within the steam client. (We're lucky Steam works, it's a better games client than the Mac App Store dreams to be, but that's also not saying much either.)
