This thesis investigates how role-based crafting systems affect cooperation in multiplayer survival games. Using design science methodology a prototype game, Back To The Stone Age, was developed where each player takes on a unique role (cook, blacksmith, builder) with exclusive crafting abilities. The prototype was evaluated through playtesting and a survey. Results show that specialization encourages communication and interdependence among players, which strengthens collaboration. However, it can also lead to frustration if progression critical items are overly restricted. The study presents design principles for crafting systems that support meaningful cooperation and recommend balancing autonomy with dependency in future game design.
