I also really enjoyed cult of the lamb: https://store.steampowered.com/app/1313140/Cult_of_the_Lamb/
It's a game where you are a little sheep creature that runs a cult. It's a mix of a management game and a roguelike since you go on runs to fight the games main bosses and get items to bring back to improve your cult.
Art style kinda reminds me of Klei's Don't Starve and is probably one of the most impressive parts of the game
Though this one is more well known. Still, I hadn't heard of it before so I think sometimes games with even a big following like this one can stay off the radar a bit unless they are truly massive.
Oh wait I forgot my favorite of all. Although idk how popular it is because its not on a standard platform

This game is incredible. Genuinely like probably the best game I've ever played. It simulates an economy fairly accurately (using the different colonies outputs and inputs to determine prices dynamically). In addition to this colonies can be hurt by you or other parties, affecting the prices of items on the market significantly so you can try to make your money on this margin.
There's space fleet battles with a complex ship modification system. There's colony management, it has an interesting early game and it keeps your interest as you get further in the game with new challenges.
It is $15 dollars and is technically in early access (which tbh is a steal). Though in practice my experience with it is not remotely reflective of it being early access. It's a little like how dwarf fortress was in early access (although unlike df before the steam launch there is a frontend that's really solid).
