Arcturus: The Curse and Loss of Divinity (악튜러스) is a Korean developed PC role-playing game created by both Gravity and Sonnori. The title was published in South Korea by Wizard Soft on December 14, 2000 and is often considered a classic that helped lay the ground work for Gravity's Ragnarok Online, a very popular MMO that shared the same graphics engine as Arcturus. A few years later, Nihon Falcom released Arcturus in Japan on June 30, 2003.
If you are wondering what are my thoughts on this game then check out my review here:
Fans of Ragnarok Online will probably recognize the look of this game. Well this game is made by Gravity and use the same engine. You can tell this is one of their early games as it is really janky and buggy. With everything I went through with the game I can't recommend it.
