I did "look back" for certain AAA games that either don't work on Linux or DO work but their launcher doesn't (e.g., Blizzard), but AAA game companies have done me the solid of hypercommercializing themselves into unbearable mediocrity. So, even if I want to play one of those games now, I'm not too hurried to wait for a few years so Proton support makes it available (plus you get it cheaper, with bugfixes, all DLCs, and your hardware can run it better).
I play wow, ow2 and such just fine from the launcher. so give it a try again if you've been avoiding it.
If you can't understand the political, philosophical and sociological nuances of selecting between Windows and Linux as computing environments, and why this is more than just a simple UI preference, that's something you should work on.
Sarcasm is also something you should work on.
See you next time.
I just love Gnome.
