Gekkeiju Online is a 3D MMORPG developed by a Finnish indie software company, Coolhouse in 2003. It incorporates anime-style characters into a medieval fantasy world.
Gekkeiju Online was a GameOgre.com online game of the week, highlighting the MUD-style gameplay which is considered more in-depth than regular MMORPGs.
A completely redone version of Gekkeiju Online launched to public beta test in January 2010.
There are 5 character classes available in Gekkeiju Online – warrior, commoner, magic user, divine arts and dark arts. Each of the character classes has its own set of guilds that can be joined to learn skills and spells. The character class also decides the skills and spells character learns automatically during the first 10 levels.
Warrior is the very basic fighter class. Their guilds specialize in melee, ranged attacks and animal taming. New players always start as warriors.

Commoners are a combinations of spell casters and fighters. Their guilds include for example bards and merchants.
Magic Users are the strongest users of magic. They can learn spells from defensive to offensive.
Divine Arts are a spellcaster class that uses divine spiritual magic such as healing-spells. Divine arts can also learn some combat skills.
Dark Arts are the evil counterpart of divine arts. Dark Arts spells are focused on damage used to supplement melee combat skill. Their guilds include death knights and fallen priests.
