Choices Matter: The Mechanics of Choice in Interactive Narrative SARIANANTRANIG AREK 2019 Interactive choices have become popular in today's games and stories. But how do choices work? This thesis examines the 'choice' as a form of expression. Some choices are like a quiz - they have a right answer. Others exist to help you explore a story from different sides. However both of these underutilise the choice. This thesis argues that the best way to use the choice is as a tool for self-reflection. By saving a person's set of choices, a game or story can respond to them in a way that's unique and helps them to grow as a person.
