This game like most games is about fighting, killing, and winning. But this game also has, unlike most games, a very strong community aspect. It is a massive world, where in games like Diablo 2 multiplayer, which has many worlds, that even you can host yourself;Ragnarok is one big role-playing world, in which everyone interacts with everyone.

The background and storyline of RO Zeny is from the original animation of "RO Zeny"(?) written by Myung-Jin Lee.
The word "RO " means "The destruction of the world in the war between the gods and the forces of evil, led by Loki, the evil son of a giant, twilight of the gods" which is derived from the Norse scripts.

The last game the Gravity created was called "Arcturus"(?) which I don't know anything about, was the original construct of RO Zeny, but was unsuccessful for reasons I don't know. I'm guessing though, it was too much like other game on the market, and to make RO Zeny stand out from its competitors, there was its upgrade to a 3D environment, with the 2D sprites as the characters, and RO Zeny to finish it off, the Back Ground Music (BGM) and various other music was composed by TeMP, Ragnarok Zeny to make it that little bit more unique (the BGM absolutly rules in this game).
