RF Online is a very unique MMORPG. One of the few that are SiFi. And SiFi/Anime. And one thats actually free and good. It has become very popular, and is even getting close to have more members than World Of Warcraft. Unlike WoW, if you want to play this game, you do not need to delete any of your other games to make room. But when you first try to play, you have to wate 1 to 2 days, for that there is so many updates that it downloads. But it is worth it. Right now it is on Episode 2, so sucks for you for missing Episode 1 :P
I will break down the races for you:
Bellato: The Bellato Union utilise machines and some magic in their culture. Renowned for their great mechanical minds, intelligence and hand-eye coordination, the Bellato can construct huge armored battle mechs and weapons to use in the war. Though they are physically strong and intelligent, the huge gravitational energies from their home planet have left the Bellato with smaller builds. The Bellato are experienced traders and their financial minds and greed have driven the need to extend out to other planets, to colonize and claim resource. To expand to the rest of the universe, the Bellato have to ensure that the Novus Sector doesn't fall under the supremacy of the Accretia or Cora. This desire to expand and grow will no doubt leave the galaxy engulfed in turmoil and chaos.
Cora: The Holy Alliance Cora is a spiritual civilisation with a firm belief in religion and the magical arts. Though the history of the Cora has been built on religious wars, which has created multiple states and nations, the country is strongly unified through its core religious beliefs. The Cora people, united as the Holy Alliance, now battle for their survival using the magical powers drawn from their spiritual beliefs, and traditional weapons blessed by their god, Disem.
Accretia: The Accretian Empire follows a totalitarian regime where goals are for the Empire, a thought that is embraced by its followers. There is no feeling when it comes to the destruction of other races and for good reason, for the Accretia are a race of mechanised units with a materialistic thinking. The Accretia are proud to be the strongest and most formidable race in the galaxy, and are proud of the huge weapons they have created to kill men, women and all things living. Their need to expand to the further reaches of the universe to become even stronger is paramount and a key driving force to their being. This has inevitably led them to the Planet Novus and the arcane civilisations it plays home to.
