Proton can make games from the windows store that I already own work on Linux? Proton can make games that are borked rated on protondb work?

I love Linux as much as the next tech nerd, I have a SteamDeck that I essentially use as a laptop when away from home, and I tried dailying Manjaro on my main machine for a couple months. Proton doesn’t solve everything.

I can totally understand running windows on your main gaming machine, as that’s what I do. I don’t like it, but all of my games work. I also don’t want to have to re-buy games on Steam that I own via the Windows store.
