If you needed any more evidence that the free-to-play MMO model is in, here's some more. Codemasters' ArchLord recently re-launched as a free-to-play, and now the developer is looking to drum up renewed interest for another Korean MMORPG it has published in the States, Rising Force Online, by offering it as a full free-to-play without subscription fees.

RF Online blends traditional fantasy and sci-fi elements. Players can choose one of three races to compete against the others for dominance in deep space. As an incentive to new players, a new expansion, Episode II: Pioneers of Novus will also be available for free.

Ed Relf, Codemasters director of marketing, said, “Moving RF Online to free-to-play game marks yet another milestone for Codemasters Online and the wider industry. We have proven with ArchLord that has been downloaded over 1 million times the potential success that can be experienced and we are pleased to be in a position to re-launch RF Online using a similar model. We invite players from around the world to download the game for free and join us in Novus."
