Oh, but there is no change in my case, because my previous dual boot was still only 2 distros of Linux :D, no Windows at all. Regarding games' library – sure, nominally all games have Windows support and only part of them comes with Linux installer. However Wine, Proton, DosBox and other tools make us able to actually play most of games.
As I prefer classics, I'd even say that I've got better support on my platform that Windows users, because:
a) most of titles runs well out-of-the-box under Wine – which is not always easy on e.g. Windows 10,
b) easily created in PlayOnLinux sandbox environments gives me much better control over Windows version and libraries used, which is impossible if you're just locked in some specific version of Windows as your OS.
Well at least you can play most games.....I could never switch as i'm too used to MS's OSs and don't want to relearn the wheel...but good on you for being happy with your setup. :)
