Despot's Game: Dystopian Army Builder is a rogue-like tactics army battler that I was absolutely in love with when it first entered Early Access and now on the Steam Deck I love it all over again.
You build up a little army of fleshy people and equip them with all sorts of weird combinations like: a bow and arrow, a sword stuck in stone, a rabbit in a hat, a stale pretzel, an American football and the list of weird weapons goes on and on. When ready, you run through dungeons room by room and face off against various robotic creations (and other horrors) while your people auto-battle. It's thoroughly odd but really engrossing to play through.
It's closing in on the 1.0 release, and a new update rolled out recently which amongst other things, added in controller / gamepad support. Naturally, I took it for a spin on the Steam Deck and apart from some tutorial quirks, it feels really great to play on it. Can easily see this getting a Deck Verified rating once it's more polished.
