RF stands for Rising Force. It is a 3D Sci Fi MMORPG that is set in a futuristic world in the planet of novus wherein there are 3 parties: Accretian Empire, Bellato Federation, and the Alliance of Cora, all of which are fighting to control the natural resources of the universe.

It has great music in it, skill system is different, economy is controlled by a large player, graphics are of high quality, and there is a goof tutorial phase. However, combats are repetitive and sometimes it is very difficult to beat monsters even when you are still new to the game.
Creating characters are simple enough. Just choose your party and groom your character. Classes are divided into four namely: Warriors, Rangers, Specialist, and Spiritualist. Warriors can take more damage; rangers needs distance for effective combat; specialists can uses different weapons but are weaker unlike the warriors; and spiritualists uses force or magic to cast spells in combat. The Cora Alliance are more of spiritualists while the Accretians are more on being warriors. The Bellato federation specializes in mechs for battle.
RF online is properly innovated in terms of the skill system. You gain skills points when you upgrade level. Skills will make you gain experience and level up. The skills can go up in certain number of times becoming more effective in combat. The mechanics of the game are simply interesting and there are many quests to be accomplished.
The weapons, even at the start of the game are just overwhelming. The essence of challenge that you will have to gain this skill before you can have this weapon is just missing. So, even if your character is still weak, you can use powerful weapons. The idea of improving your character is just simply useless if you are already equipped with high calibre weapons.
There is the contribution points feature wherein the player with the most contribution points gets to lead the party they belong to. They can be achieved through the quests or PvP combats. Also, when you reach level 30 and level 40, your character can advance to a new class. The music imbedded is just unremarkable. Unlike other games which have music that are not really what you call connected to the game, RF online does have the appropriate music in it.
RF online charaters are somewhat mixed up. In combat, you get to fight monsters that are way beyond your skill level even when you are just starting the game. Maybe this explains why you are given the option to choose powerful weapons in the beginning to beat these monsters. It may make the game unique on its own but it just does not make sense why it has to be the other way around. Maybe we were just used to the traditional newbie needs weak weapons to fight weak monsters. However, in this game, monsters tend to be stronger making it difficult to defeat.
Overall, RF online is a great MMORPG. High quality image and with a good user interface makes it stand out making it par to its Sci Fi setting. The weapons and the distribution of characters are just somewhat weird though.
