I switched all the machines at https://lanparty.house over to Linux a couple months ago. So far, we've experienced noticeably fewer problems on Linux compared to Windows. Stability and performance are better. I can't think of one game we tried that didn't work. And wow is it nice not to have all the ads and crapware in our faces anymore.

It keeps surprising me how many people don't care about some of the most popular games today.

Go back and look at some of the 00s and early 10s E3 presenations from the big three and its very cringe inducing how focused they are on a teenage boy demographic and appearing edgy and how blatantly sexist they are in their language. For example, at the E3 conference where MS announced xbox live (2004?) they explictly said that girls don't play games (there were actually plenty of girls that did play games at that time), but they might want to use xbox live to design t-shirts to sell to boys on their online marketplace. This was also still the era of booth babes trying to pull in men to booths with barely dressed women. Nearly every game ad was just a wall of exposions and violence or just the latest NFL game.
Today you have fully grown adults in their 30-50s with very different tastes and you have a lot lot more women and girls playing.
On top of we have a lot of diversity in who creates games and the kinds of games they can create and still be commerically successful. Lots of interesting narratively focused games, puzzles games, platformers, and more artsy games. But if you want your multiplayer shooter battlefield and CS2 are still there for you.
