I was enjoying this game. It loads very fast. Very good graphics. Stable. The kingdom wars are no stress. Easy game to just play with no real obligations and responsibilities. Only problems were that the rewards are very stingy and battle system is not made for hardcore gamers. In other games if you are good you can continuously siege for resources without any big down time. Rival Kingdoms however isnt that smart. Every single battle costs a battle stone. Once used to recover one battle stone takes 20 min and will stop at 5. So after u spend your 5 stones you have to wait which is counter productive. Another flaw is that you cannot just keep looking for oponants that you can actually fight. Once u use the battle stone the base you encounter is the one u must battle. 

WARNING!! SPACE APE IS A SOCIALIST DEVELOPER. They will delete your account for absolutely no reason and you will not be compensated for any money spent at all. It happened to me yesterday. I have no idea what i did. So there is a reason Space Ape has a bad reputation. They ruin their own games and destroy their own clientel by doing shet like this.
