## Context and limits

A map of 160 techniques for analyzing interest, returns, costs and pressure on the player. Involvement in itself does not mean dependence; the presence of separate mechanics does not determine the diagnosis or prove causation. This is the author's classification for critical analysis of design, and not a scientifically established list of the causes of gaming disorder. Assess context, audience, voluntariness of participation, and opportunity to stop.
