To be fair, the number of times I’ve had to tinker has drastically reduced since the Steam Deck came out. I used to check protondb.com before installing a game, and now I don’t bother. Games tend to “just work,” and it’s getting better all the time.
I’ve been Linux-only since before Steam came to Linux, so I’ve seen the entire evolution from “try your luck w/ WINE” to “click play and it just works.”
Now is a great time to jump into Linux gaming, and if you stick to the Steam Deck Verified titles, you’ll probably never need to tinker. If you venture out to “Steam Deck Playable,” you’ll probably never need to tinker. Honestly, even a lot of the unsupported titles work just fine w/ no tinkering.
