The big problem is that the games that don't work now are for political / financial reasons more than technical reasons--notably incompatible anti-cheat systems or developer refusal to enable the Linux support for their chosen anti-cheat. And these aren't small titles either: PUBG Battlegrounds, Call of Duty Modern Warfare, Fortnite, Destiny 2, Genshin Impact, just to name a few.
