Its all about your money--bring your unlimited credit card

Interesting concept: plan, build, and maintain your own kingdom with the help of others. It can be fun, but what starts as a free app, turns into an extremely expensive game very quickly. To survive and excel in KAW requires you to buy nobility points and crystals, both of which, quite frankly, are outrageously expensive. If you make some errors in your build, and you want to reset your buildings, you will lose any money you have put into the game. Recent "events", designed to make the game more interesting, also require lots of crystals to achieve the higher levels. Their war system is so broken, only those who have spent 10s of thousands can hope to win. You have been warned.
