Ragnarok Online is a massively multiplayer online role-playing game, based on the manga Ragnarok written by Myung-Jin Lee. The game's focus is squarely on community, having players interact with each other and shape the storyline as they get wrapped up in Ragnarok's plot.

The game sports anime-style graphics, featuring 2D characters on top of 3D backdrops, as well as music and jingles composed by TeMP.

RO Zeny offers players two different experience levels. Character levels allow for stats adjustment, while Job levels let players pick new skills that depend on the player's assigned job class -- of which there are seven: novice, swordman, archer, mage, merchant, acolyte, and thief.
