When developing commercial games, difficulty levels are carefully designed to satisfy many game players. Inappropriate difficulty levels can cause stress to players, leading them to quit the game. In recent years, a system called "dynamic difficulty adjustment," in which a computer analyzes the player's playing situation and adjusts the difficulty to an appropriate level, has been attracting attention as a solution to this problem. In this study, we use biometric sensors to measure and analyze players' biometric information during game play to clarify the relationship between game development and emotions. Furthermore, we will develop a game that can estimate changes in emotion in real time using biometric sensors, automatically adjust the difficulty level of the game according to the emotion and verify whether the adjustment is appropriate for the player. The results obtained from the experiment did not provide definitive indicators or evidence of usefulness, but suggested the possibility that the emotions that are likely to be expressed differ depending on the degree of difficulty and personality. The results obtained from the experiment revealed that the emotions that were likely to be expressed differed depending on the game scene and the difficulty level.
