Avante! Atlantis is an upcoming turn-based strategy game that looks like you're playing a board game with a clever 2.5D style. The developer recently announced full Native Linux and Steam Deck support. There's a demo available right now too which they keep updating for you to get an early taste of what's to come.
More about it: "Amid global conflict and scarce resources, the lost city of Atlantis has mysteriously resurfaced. Rich in natural resources, it quickly becomes the focus of every major nation’s ambitions. But Atlantis didn’t return by chance. As battles rage across its ruins, a deeper mystery begins to unfold...one that could reshape the world."
Getting some Advance Wars vibes from this one for the mixture of the level and battle scene style, but at least unlike other very similar games to Advance Wars, the overall aesthetic is more unique.
