Game context

  1. The 0.6-second game tick

    RuneScape's servers advance the world in 0.6-second game ticks, so every new system has to fit that rhythm exactly.

  2. Decades of live content

    Launched in January 2001 and still updated, so new systems sit inside a large existing world, economy and player base.

  3. Desktop, Steam and mobile

    RuneScape came to Steam in 2020 and to iOS and Android in June 2021, alongside its long-running desktop client.

  1. AI citizens

    An open-world city needs non-player characters that go about their day and react to the player.

  2. Persistent ownership

    Players own property and vehicles, so the backend has to keep that state safe between sessions.

    In-city jobs connect what players do in the world with records the server keeps.
