It's like this. You eventually got Starcraft2 to work. That means Linux can run Starcraft2, it's in the "Runs" category. Games like League of Legends, which have kernel level anti cheat, are in the "Won't Run" category.
I have an Nvidia card and use mostly Ubuntu (mate), also for gaming. It's even a problem now, because I would benefit from a hard divide between the gaming and working\studying system (I have a gaming user in backlog). On Linux it's mostly KSP, Factorio, but sometimes DeepRockGalactic, Valheim, Euro Truck Sim or Warhammer: Total War1\2\3. These games work flawlessly or with <10%fps hit.
There are games that kind of work - Ancestors: Humankind Odyssey, Cyberpunk, Hunt: Showdown. But you lose comfort and I'd rather just play them on Windows, than suffer decreased functionality on Linux. I know that some of it (definitely Cyberpunk) is only because of NVIDIA.
When buying games I usually don't buy Windows only games unless there is a very good reason. And I quit League of Legends and WRC rally because of anti cheat scam. I feel scammed after putting lot of money in a game and suddenly losing the ability to play it.
Comeon. If a customer bought a game that says it runs on linux, they should be able to play it on linux well, not just launch it and quit within 5 mins.
I get you have the ideology up in your head, but don't lie and embellish linux to this degree. The attitude just turns people off.
It's like saying something works on "laptop" without specifying whether it's a Thinkpad or a Chromebook or a Macbook.
Actually there was one thing I couldn't do but this isn't unique to NixOS. I tried to install a GTAV mod that allows you to ride your smart bike trainer in game: GTBikeV. The mod can be installed, but the Bluetooth doesn't work. This is a WINE limitation.
None of those games say they run on Linux.

Every game I've purchased that actually says it runs on Linux, has worked beautifully on Linux (stellaris and factorio come to mind). Most windows games work beautifully on Linux too, but Blizzard isn't lifting any fingers to make it that way.
And I choose to use Windows for most of my personal computing, due to my gaming preferences, some needs (concussions + poor eyesight means things like scaling and brightness controls and refresh rate matter a lot to me), and my preference for DxO PhotoLab (which isn't Linux compatible.)
