Gaming on Linux is so good now I know multiple people who switched their gaming PC to Linux and have no intention of going back. Then there's Steam Deck, which has 3million+ users alone. 3.6% of Steam users are playing on Linux[0], which is kind of insane if you ask me, especially when only 2.2% are playing on MacOS.

Install Steam in Linux and notice you can play the vast majority of your library. There are some online multiplayer games that won't work due to anticheat[1] though that seems to be improving over time as well.
