Saga bills itself as "the world's first persistent online real-time strategy game". The game blends traditional fantasy RPG elements with RTS and trading card games. Five warring gods are at teh heart of the nations and races in the game, and each has its pros and cons. The game is free to play in very limited form, or fully unlocked for $19.95. However, upgrades in the form of "booster packs" must be purchased with real money if the player wants to gain new troops, regardless of whether your client is free or a paid download.
