RuneScape is a Java-based MMORPG (Massively Multiplayer Online Role-Playing Game) operated by Jagex Ltd. It has approximately five million active free accounts[1] and more than one million paid member accounts.[2] It is a browser-based game with some degree of 3d rendering.

RuneScape was created by Andrew Gower, the creator of DeviousMUD, the forerunner to RuneScape, in 1998. Rewritten and renamed, the first version of RuneScape was released to the public on 4 January 2001. Since its release, the game has been noted for its free-playing option, its simple interface, and its accessibility on most web browsers. RuneScape takes place in the fantasy-themed realm of Gielinor,[3] which is divided into several different kingdoms, regions, and cities.[4] Players can travel throughout Gielinor on foot, by using magical teleportation spells and devices, or mechanical means of transportation.[5] Each region offers different types of monsters, materials, and quests to challenge players.

Like many other MMORPGs, there is no linear path that must be followed. Players are shown on the screen as customizable avatars, setting their own goals and objectives. Players can engage in combat with other players or monsters, complete quests, or increase their experience in any of the available skills.[6] Players interact with each other through trading, chatting, or playing combative or cooperative mini-games.
