Darnit, I miss Tabula Rasa.
I can say that both City of Heroes and Phantasy Star Universe run wonderfully through Lutris/Wine, though perhaps they're not the best examples, being Old. The only real frustrations I've had of late with my Deck are Operation Neptune, because whatever its setup, it doesn't like to play the sound for me (some setting or another, and good luck finding the right command line switches) and Stardew Valley -- setting it up with mods is a bit frustrating. Works fine in vanilla, so I have a farm going on each side.
With the continued enshittification of everything Windows, I expect the gaming market to be overtaken a bit more swiftly than most.
