매치 3게임에서 플레이테스팅 방법은 전통적으로 사람들을 이용하는 방법으로 지속되어 왔으며, 최근에는 딥러닝을 이용하는 방법으로서 게임의 장르적인 특성들을 고려해서 각 레벨에 대한 플레이 데이터를 이용한 지도학습 방법과 환경과 상황 그리고 보상을 통한 강화학습 방법들이 연구되고 있다. 본 논문에서는 매치 3게임에서 강화학습을 이용한 플레이테스팅의 향후 연구 방향성에 대해서 기준을 제시한다.

The difficulty of the game is closely related to the fun of the game. However, it is not easy to determine the appropriate level of difficulty of the game. In most cases, human playtesting is required. But even so, it is still hard to quantitatively evaluate difficulty of the game. Thus, if we perform quantitative evaluation of the difficulty automatically it will be very helpful in game developments. In this paper, we use a path finding algorithm to evaluate difficulty of exploration in a game level. Exploration is a basic attribute in common video games and it represents the overall difficulty of the game level. We also optimize the proposed evaluation algorithm by using previous exploration histories when available area in an game level is dynamically expanded and the new search is required.

This study attempted to identify differences in user experience and app game fun, satisfaction, use intention between fitness app games at different level of interaction design. The playtesting method was conducted on 100(male 50, female 50) university students using 'Enjoy Your Fitness', a fitness app game developed by The Center for Health Communication Studies. The results found that more interactive app game is higher in the level of user experience such as fitness accomplishment, flow, and interest. Fitness app game's fun, satisfaction, use intention is also higher on interactive fitness app game. As the study verified that interactive fitness app game had stronger effects in user fitness experience and user experience than general fitness app games through experimental studies, it may contribute to design fitness mobile app game for health improvement.

This study attempted to identify differences in user experience such as spatial presence, social presence, flow, empathy, anxiety, and perceived risk between simulating characters of animation and of actual userimage. The playtesting method was conducted on 60 male smokers using 'Smoking Sims', a simulation game produced by The Center for Health Communication Studies. The results found that the simulation of actual image character is higher in the level of perceived risks for smoking, spatial presence, social presence, flow, and empathy than the simulation of animation character. The study shows that identification with a game character affects user experience and enhances the effectiveness of perceived risks as well. It emphasizes the importance of game design to implement identification in serious game like a smoking cessation simulation.
