RuneScape

RuneScape is an MMORPG launched by the UK company Jagex in 2001, still continuously updated and operated today, with cumulative registered accounts exceeding 300 million.

Progression in RuneScape requires a large amount of online time; if an agent's task cycle is measured in hours or even days, the compute and time costs of evaluation will far exceed those of traditional benchmarks.

RuneScape's interface operations are cumbersome, with a large amount of time consumed by mechanical clicking and moving, which introduces noise unrelated to intelligence and makes evaluation results depend partly on operational efficiency rather than decision quality.

Game-based benchmarks face reproducibility difficulties: MMOs adjust skill values, map layouts, and quest flows with version updates, so old evaluation records may become completely invalid under new versions; the game world contains other real players and random events, making the same path difficult to replay precisely.

RuneScape's client has long been mainly click-based, with high interface information density but low automation, and the player community has developed a vast Wiki and guide ecosystem.

RuneScape uses a skill-driven progression system: players have no fixed class or level, and improve corresponding values by repeatedly practicing more than twenty skills such as woodcutting, mining, smithing, and fishing, with dependencies among skills formed through materials and finished products.

RuneScape is a classic online game developed by Jagex.

RuneScape went live in 2001.

In RuneScape, poison had no effect on cows because the damage check and the cow's mooing occurred within the same server tick and cancelled each other out.

RuneScape in 2004 was a browser-based massively multiplayer online role-playing game that successfully brought thousands of players into a single persistent world.

In RuneScape, environmental damage in desert areas was accidentally negated because an unrelated quest checked all player positions every 15 seconds, overriding the desert damage check logic.

RuneScape's early success was largely attributed to its extremely efficient network communication design, in which almost no communication was wasted.

RuneScape is notorious for its spaghetti code, especially in versions prior to 2007.

RuneScape employed byte-for-byte 1-to-1 substitution encryption, making the encrypted data size exactly equal to the pre-encryption size with no bloat.

RuneScape developer Jagex has published an official position on the use of generative AI in game development.
