Quoting Kylees Mama:" lol a my little pony game? what do you do on it?"
Yes! A free my little pony game that sucks you in and won't let you go! Lol
From what I gather, it is when "Nightmare Moon" takes over and makes it night and Twilight Sparkle is using her magic to make it light again and defeat Nightmare Moon by using the Elements of harmony (which are in random parts of your land that you have to unlock lol). It is almost like the SIMS. You buy shops and the other ponies; employ those ponies into the shops and collect bits and gems and stuff AND play games with each pony to level them up
