This is one of those money-grabby resource accumulating games, but I'm pretty fascinated by its sheer disregard for balance in favor of cash shop dominance. Either way its a neat game.
You start out with a little realm of your own, but you can build tunnels to other realms. Some are dangerous and you may walk into a massive army, and some are safe places where you'll find amassed ponies and random signposts with movie quotes.
Its like a long term civ sort of game minus the tech trees and stuff. I love that resources are something to be fought over, though. I sent an explorer through a conquest tunnel and there were at least 100 archers ready to kill him if he went a step too far.
If you want to see my realm (even though it's empty) my realm number is 48737 (38,26).
