The document discusses the discovery process used by Mind Candy to design games, which involves ideating many alternative ideas, quickly prototyping them using lightweight tools, and validating ideas by testing them with users. It emphasizes finding fun as an adventure rather than a planned journey, and using mastery of players and types of fun to guide discovery. The process is iterative, moving between ideation, validation, and refinement of ideas to efficiently find the most engaging concepts before committing to deadlines or full development.
