Etherlords is the latest smash hit RPG for the iPhone and iPad, this one being very loosely based off of the old PC RPG by the same name, also by NIVAL. This game has three forms of currency, or "currency" as it were. Ether is the primary one, the one in the blue bottle that's used for almost every purchase in the game. Etherlord Valor, sometimes referred to as Honor, is the one in the green bottle that is more rare and has less uses but is very valuable for enhanced fusions. Matter is used to rebuild the world.
