Background:
Ragnarok Online is a MMORPG set in the land of Midgard, where after centuries of peace, the world is in danger. As one of seven job classes, players can explore the world of Midgard online.

Gameplay:
Players interact with each other and shape the storyline as they get wrapped up in Ragnarok's advanced plot. 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. Your character moves through the screen by a simple
mouse click. This allows you at the same time to attack an enemy or pick up an item.
