Of course the underlying mechanic of the game has nothing to do with defeating Nightmare Moon, but is instead more of a combination of collecting/city building, ala Pokemon/Sim City. As you proceed through the game you lure individual ponies from the show to your town by constructing their homes. Once they have a place to stay they are dropped off via hot air balloon and are now a permanent resident of your town (so long as you don’t remove their home of course) you may then build different businesses such as apple stands and spas for the ponies to work at, allowing them to make your town money and element shards. And there is the interesting bit, as bits, the game’s currency, are the key to almost all basic progression. Want to get another pony? You’re going to need bits. Another business? More bits. Expand your build area by using the magic of friendship to push the darkness back? That’s going to take an increasingly large amount of bits.
