Sword of the New World: Granado Espada. Launched in Korea in the Summer of '07, developed by IMC Games Co., and published in North America by the K2 Network, SOTNW (that's a mouthful!) is the very first game to incorporate an RTS style of combat (think Starcraft, but reduce it to three zerglings) with the MMO genre. While the game was originally slated to be subscription based, it has since gone the way of most Korean MMOs - free to play, but with lots of items that can be purchased in the cash shop.
