Unrailed! from Indoor Astronaut is a great co-op multiplayer game that's good fun with friends, and now works properly on Steam Deck / Linux again.
Specifically, they fixed up the Native Linux version of the game, which was having problems crashing with the latest SteamOS release. Valve actually rated the game Verified with the Native version being the default. They've also updated the version of SDL they use which they said "should solve several issues where controllers could not get recognized".
I did a play-through only recently with family, and had to end up using Proton as the Native version just wouldn't work. Nice to see it properly fixed out of the box now. While it's good that the option was there it's still quite annoying to see a Verified game just suddenly broken like that. Once again, Proton saved the day. At least in this case, the Native version is still actively supported by the developer.
