Game development costs a lot of money. Thus, in terms of cost-saving, game companies produce prototypes and undergo several tests and modifications during the development period. In this paper, we proposed a brainwave signal analysis system and linked it with the game to measure the player's emotion through brainwave analysis experiment and tried to solve these problems. The brainwave signal analysis system proposed in this paper is capable of various applications according to various development situations, such as the progress of the game, events, etc. in obtaining simple figures over time by linking games, and collecting the tester's responses according to development intentions, so there will have to be continuous additional research.
