Lucinda Green's Equestrian Challenge is the best horse game for PC. You can disagree with me, but I will stand by this statement. I can't even begin to tell you how much fun I had playing this game. The graphics are great and the attention to detail will make horse lovers so happy. This is a 3 day event, also know as eventing, horse game which means there is dressage, cross country, and show jumping. Each component is challenging but not so hard it is frustrating. Of course your also get to customize your horses including breed, coat color, and markings. Your avatar is also fully customizable from their gender to hair color. As you move through the game you get to unlock new 2 star, 3 star, and 4 star competitions. You will also have access to new tack, accessories, riding gear and more by winning competitions.
