An MMORPG (Massively Multiplayer Online Role-Playing Game) is an online-only video game that unites hundreds of thousands of players from many countries in one exciting game world to create a rich and interactive community. MMORPGs usually run on monthly payment subscriptions and provide exciting content for players all around the game world to take part in together. MMORPGs are full of quests, exploration, excavation, monster slaying, PvP (player versus player combat), and many more adventures.

RF Online stands for Rising Force Online. It combines science fiction and fantasy to create a unique theme, different from any game that preceded it. The game focuses on three races and their ultimate struggle for power on a planet called Novus, in the Novus Sector of the galaxy. There is a great emphasis on race-versus-race combat in RF Online.
