RF Online is a 3D MMORPG originally named 'Rising Force' but then shortened to RF Online. The game was developed by CCR Inc. and released in South Korea. It is a mixture of fantasy and futuristic sci-fi action in a full 3-dimensional environment. RF Online takes place in a distant planet in the Novus system where magic exists alongside high technology. The game is centered on the conflict between 3 races fighting over for the control of precious resources in order to advance to the goal of their races.

RF Online CP is the local currency for one of the three races, the Accretians race. Each class has its own currency. CP can be earned by killing monsters throughout the game and mined out of the gold mine. Players can exchange gold for RFO CP at the "Coin Exchange" operated in the HQ. RF Online CP value fluctuates upon the conversion of resources generated in the mine. The more conversion of resources to currency the less value RF Online CP is. The economy of the game is carefully adjusted every twenty four hours. A re-calculated tax rate is applied in order to control inflation. Players need to pay tax when trading items, just like in the real world.
