RuneScape
Runescape is massive 3D online multiplayer game. Your goal is explore the world, fight monsters, embark on quests, foil villainous plots and interact with other players. The game is open-ended, so it unfolds in whichever way you want it to! You start on Tutorial Island, where skills trainers learn you the basic skills you need to get started. After completing the tutorial you will be sent to Lumbridge, from which you can start your adventures. Good luck!
