Emil Chronicle Online was a 3D Japanese fantasy MMORPG with anime-style graphics. Set in the land of Acronia, the game featured twelve classes spread among four races, each with a particular advantage (agility, magic, or strength). Along with a series of quests and battles, the game featured a few standout modes including its marionette system, where players could transform their characters into marionettes, which were Pokémon-like surrogates. Marionettes could live in the world even when players had logged out. There was also a standard pet system outside of this. Players could also turn their characters into weapons that other people could use, gaining both experience. PvP was in RvR format, and massive battles were scheduled regularly in advance for different level groups.
