AdventureQuest (also referred to by its website name BattleOn or abbreviated to AQ) is an online Flash-based single-player role-playing video game started in 2002^[1] and currently developed by Artix Entertainment.

A one-time "guardianship" fee was introduced in 2003, allowing the player to access extended in-game content. Ownership of the game transferred to the newly formed Artix Entertainment in 2004, and a server population cap was added for non-Guardian players in May of that year. In 2005, a microtransaction system was put into place. In response to criticism that server restrictions made logging on for non-paying players difficult, in October 2006 Artix Entertainment introduced a server in which a player could log on at any time, but with a tight level limit. In July 2010, the server cap was removed permanently.
