I used to feel like this, but then ran into games like S.H.O.G.O:MAD and Terminus, and The Bard's Tale - those have native Linux ports, and they're pretty much un-playable these days. Using Proton, I can run even problematic old games like Dark Messiah of Might and Magic (that won't even run on Windows anymore!).

I feel like insisting on Linux native ports is letting perfect be the enemy of the good, and that native ports don't necessarily guarantee anything at all.

I certainly do appreciate developers who can provide native ports, though. In the end, I just want to relax and shoot alien space nazis in the face, and not think about how to get the alien space nazis to run on my machine.
