【讲座介绍】An important problem in single-player video game design is how to sequence game elements within a level of the game. Each element has two critical features: a reward and a degree of difficulty. The latter property is a distinctive feature of video games. Unlike services or passive entertainment, video games often require a concerted effort to consume. We study how to sequence game elements to maximize overall experienced utility subject to the dynamics of adaptation to rewards and difficulty as well as memory decay. We find that the optimal design depends on the relationship between rewards and difficulty, leading to qualitatively different designs. For example, when the proportion of reward-to-difficulty is high, the optimal design mimics that of more passive experiences. By contrast, the optimal design of games with low reward-to-difficulty ratios resembles work-out routines with ``warm-ups'' and ``cool-downs''. Intermediate cases may follow the classical ``mini-boss, end-boss'' design where difficulty has two peaks. Numerical results reveal optimal designs with ``waves'' of reward and difficulty with multiple peaks. Level designs with multiple peaks of difficulty are ubiquitous in video games. In summary, this paper provides practical guidance to game designers on how to match the design of single-player games to the relationship between reward and difficulty inherent in their game's mechanics. Our model also has implications for other co-productive services such as training programs.
