Cattle Country is a really nice western styled life and farming sim that's a good pick for fans of Stardew Valley. Now with a big content update! ICYMI: See my original thoughts on it.
What is it? A cosy frontier life-sim where players can build their dream homestead, raise livestock, craft tools, and carve out a peaceful life beneath the wide Western skies. While you can also romance characters, it's not all sunshine and rainbows - there's bandits that come along too, all part of life on the range.
The developers just released the "Beneath and Beyond" Update and it sounds like a good one. With expanded underground mining, and multiple big new features for all the above ground adventuring you'll be doing.

Update Highlights:
- Expanded Mining System – New mine levels, rarer resources, environmental hazards, and surprises waiting in the dark. Dig deeper than ever before and uncover secrets beneath the soil, from glittering gems to long-forgotten bandit loot.
- Hay Dropper – Automatically feeds hay to your livestock, giving you more time to enjoy the open range.
- Scratch Post – Place it in your barn or coop to keep animals happy and content.
- Aquariums – Show off your prized catches by displaying fish in beautiful tanks right at home.
- Horse Whistle Tune – Play a tune and call your trusty steed from afar, perfect for long treks or quick getaways.
- Walleye Fish – Now available in lakes during spring and fall. It was previously uncatchable, but no longer out of reach for patient anglers.
There's quite a lot more including plenty of bug fixes you can read in the announcement.
