Pony Ranch

Summary
Basically a farm-themed, standalone add-on for "Wildlife Park". This explains some of the weird interface (giraffes!) and gameplay elements, where one of the main goals is to attract visitors for your farm.

Game Design
Top-down view; isometric, very pixelated graphics.

Gameplay
You build a farm, hire workers to grow food and care for your animals. If they are happy, they'll reproduce and you can sell them(only the animals, not the workers). You can also build infrastructure to attract visitors and sell produce.

There are 8 available horse breeds, each with slightly different needs: Shetland pony, Haflinger, Westfale, Hannoveraner, Arabs, Appaloosa, Tarpan, and Przewalski. Other animals are bees, chickens, peacocks, cats, dogs, rabbits, pigs, goats, sheep, and cows.

Riding Mechanics
No riding.

Differences between Releases
There is a 2017 Steam release under the name "Farm World". Might be somewhat updated going by the pictures, then again, looking at the reviews, might not be.

A free-to-try mobile version of Farm World also seems to be available.
