I was a console gamer for a long, long time just because I refuse to use Microsoft products, and Linux gaming was fraught except for Battle for Wesnoth and Nethack. Many hours just messing with Wine vs I turn on the machine and the game just starts, no fuss.
I've owned a Steam Deck not quite since day 1, I'm beyond delighted now that I can just buy and play Steam games. I think I've thrown maybe one game at Proton that I just couldn't get working. And things like the Heroic launcher have made GoG games (most of which already ran on Linux since they just run via DOSBox) easier than ever.
Anyone on the fence about keeping Windows around just for games: unless you play online multiplayer that uses kernel anti-cheat, just make the jump. I promise you, almost every game in your library will just work, and almost all of the rest will work after you set them to run with a specific Proton version.
