Tainted Grail: Fall of Avalon is like Skyrim but with better combat and dar King Arthur themed.

Potion Craft is a game where you run an alchemist shop, entirely stylized to look like medieval paintings.

Buddy Simulator 1984 is a game about a digital companion that likes you too much.

I could give more, but I never see anyone recommend those, and you have a lot of recommendations in this thread already.
