Don’t even need Steam deck. The Steam store has put an end to my pirate life over a decade ago.
On multiple occasions, I have found myself rather wait for sale and bought a game on Steam, than receive it for free on Epic store.
I put every single games that I have ever pirated in Steam’s wishlist (if it’s available). Then slowly buying them one by one when they goes on sale. I’m not rich by any means and it’s the least I can do.
