Don’t have any games that require those. So never ran into that problem. But I can imagine there are potential games/apps people would want that can’t run on Linux. Windows VMs might be a solution but I don’t know as I never had to deal with that.

Steam, wine and dosbox with them, you can effectively play any game worth playing. Beyond that I never needed to know.

Not every version of chmod supports that and you really don’t want your media files to be executable

Well sudo find ${path} -type d exec chmod 750 {}; to fix the folders first Then sudo find ${path} -type f exec chmod 640 {}; to fix the files

After that sudo chown -Rv my user:media ${path} and everything should be sorted

Unfortunately the XSettings freedesktop spec is trash and hasn’t been released let alone revised since 2001
