Gekkeiju Online

Gekkeiju Online was a free-to-play 3D anime-styled medieval fantasy MMORPG from Finnish indie studio Coolhouse Productions, running since 2003 with deep MUD-style systems. Players chose from nine races and five classes (Warrior, Commoner, Magic User, Divine Artist, Dark Artist), advanced levels through NPCs rather than pure grinding, crafted across 13 professions, formed parties of up to 8 or clans for dungeons and raids, fought in completely open PvP anywhere in the world, and could purchase and customize ships for naval battles. The official site has displayed an error page since May 2020, later updated to a message that the project 'may be rebooted at a later date.'
