Proton covers most games that I play, only a couple exceptions involving heavy handed anti-cheat stuff like League of Legends has now. For non-gaming Windows stuff that doesn't work in Linux I would guess that a virtual machine might work.
The joke is that the games are bad, and the communities too toxic, to be a healthy hobby.
Thereby, a person being prevented from playing is being blessed, not because there is no longer a backdoor into their system. But because they will no longer have to endure the verbal abuse of temmates and opponents.
