Palworld is a new release on Steam in Early Access from Pocketpair. A fusion of Pokémon with monster catching, farming, building and much more. It is Steam Deck Playable and does work on Desktop Linux too.
That pal in the thumbnail looks like someone on the Palworld team took a fan edit of an Egyptian themed lucario and specifically designed that pal to look just like it.
I realize this is the linux gaming sub, but it's worth mentioning that this is on Gamepass too (I still use Gamepass on Xbox even though I don't game on Windows anymore).
Make no mistake, this is an early release survival/crafting budget game. The engine itself is fairly limited and feels more like a free mmo from 10 years ago than an Ubisoft game. It's fun, though. It has all that stuff which is advertised, and I've been having fun with it. It's a Skyrim kind of enjoyment, vast and shallow, but the vastness has its own appeal.
Unfortunately this seems like the kind of game which is going to be completely ruined in about a year. It is clearly set up to farm microtransactions in the future. Right now in the goodwill period the game functions like an actual game. Some people may want them to "finish" the game before they get it, but that's not the kind of game this is. The full release is now. In a year the game will be an unplayable skinner box.
Can confirm, ran fine on my desktop machine without needing to tinker (caveat: I changed the "compatibility layer" to use proton-ge before attempting to launch it of my own initiative).
