I do not believe that _you_ are trolling with this question, but answering this is just asking to be trolled.
That said. Fortnite. Yes, I still play it with friends and cannot play it on Mac or Linux. :(
I'm sure others have similar examples. Also there are just simple things like playing with friends and streaming on Discord. Anybody streaming from Windows always comes across smooth and HD to the other participants while anybody on Linux seems to consistently be received (I don't know where exactly in the chain the problem exists, so just "received", as it may not be a broadcasting or encoding problem, I'm not an expert in this) with a lot of artifacts and lower framerates.
