There are a couple features in this game that make it stand out from the others, and they're mostly involving social features. The first is that the racing system actually matches you up with other players who are online, and actually allows you to chat with them before the race starts. This kind of real-time interaction is seldom seen in Facebook games. In addition, when you sell a horse you actually enter them in a multiplayer marketplace where players can sell horses to each other. This is a neat feature that may help set Horse Academy apart from other horse games such as Horse Gaga.
Horse Academy is a new game from a smaller developer, so it isn't without faults. The game is rather confusing for someone starting out. The game attempts to present you with a tutorial in the form of objectives but it is hard to follow the steps and do as the game is asking. There are also so many elements such as health, decorations, training, racing, breeding, selling, buying, stats, grooming, etc. that it can be overwhelming and tough to learn. We suspect that this is an early beta release and we'll see it evolve into something more polished and easy to learn.
So far, there doesn't seem to be any viral hooks in the game - which is odd. It does not seem that you can invite friends, and the game doesn't prompt you to share anything to your wall. It is possible that since this game is new, they are trying not to spread quickly. Horse Academy currently has around 25,000 monthly active users in the short week it has been out, and everyone loves horses, so we'll be keeping a close eye on it. Give it a try and let us know what you think!
