You can also do all the typical farm life activities, like gathering up prairie grass to feed your animals, or collecting horse manure to fertilise your plants. There's a new riding skill for Sims to learn, and horses can be trained up with agility and jumping skills - all of which you can put to use by entering competitions at the equestrian centre. It's even possible for foals to be born so you can raise them up from the very start of their life. On the point of horses being 'customisable,' you'll be able to choose exactly how your horses look in Create a Sim, but if that's not your thing, you can also just rescue or buy one.
It being a pack all about horses, you won't be surprised to hear that you can raise, train, and form special bonds with your horses that the leaks call 'customisable members of your family.' While the main (mane?) draw is being able to care for a horse, you can also look after mini sheep or mini goats, and your Sim can earn money by selling homemade nectar too, a returning feature from The Sims 3. According to the leak, the expansion pack is due out July 20, just under a month away.
