Proton has been a game changer. Once they get the anti-cheat systems working (and they are making progress), linux will be much more of a valid choice for gaming than it has ever been. I used to do what gaming I couldn't do without on a Windows laptop, but now I do it all on my main linux desktop and haven't booted the laptop for months. Even some of the mod makers are making tools for linux now. It's a completely different world than it was even a few years ago.

There are still games that have problems, but Valve and the wine devs and others are knocking those down one by one. So those 15 people that wanted to switch to linux but couldn't because it couldn't run their games can now do so :)
