Larp engines: what they are and how to design them

A larp engine is an element that moves the larp. It creates play, prompts players to participate and reacts to their choices. But what are these engines and how do they work? Can they be combined, creating chain effects? In this talk, we will discuss the best known (agency, alibi), and the lesser known (spatial design, affordances, motive). Through case studies and examples we will highlight how larp design is a dynamic and holistic process in which all elements can be game engines.
