Computer games should keep user's immersion for fun. Flow can be occured on the balance of user's game skill level and the difficulty level of the challenges by an immersion theory. Computer games can make automatic control of the challenge difficulty level but user's game skill makes difficult to know instantly its level on gameplay because the skill is decided by game goals, user tendency, or user experience. In this paper, we proposed a method of measurement of user's gameplay skill level that we can know the skill level instantly on gameplay. The proposed methods require to be implemented in the stages of the design and implementation of the computer game to be used. Computer games can keep continuously the balance of user's game skill level and the difficulty level of the challenges in order to occur flow immersion by using the proposed measurement method and automatic control methods of the difficulty of game challenges.

In aspect of HCI(Human Computer Interaction) gameplay is the procedure to solve the problem that gamers encounter in order to generate or discover a new rule to achieve gamers' goal. The goal of this research is to investigate the structure and understand the gameplay in aspect of affordance from ecological psychology rather than the traditional problem solving theory. This research selects 'World of Warcraft' as MMORPG(Massively Multiplayer Online Role Playing Game). Five expert gamers participated in this experiment. We record all gameplay using audio and video device. We conducted protocol analysis as qualitative method based on the verbal report and action protocol during game playing. As result, gameplay based on affordance includes selection and relation. We found that subjects selected one thing at once with attention. Moreover, we found that there were two behaviors : exploratory action and performatory action. We believe that learning, utilization, and transformation for affordance appear. The result of this research imply to suggest design guideline for game design methodology when designers develop game.

Computer games must keep the user immersed for fun. According to the immersion theory, maintaining the user's immersive state requires a continuous balance of game skill level and game difficulty level This study proposes a game skill estimation method of 9th grade that can be applied to a casual action game that can assume a zero-sum game, and additionally proposed a difficulty guessing method. The proposed methods can be implemented quickly and easily because it is a method determining by conditional mathematical expressions. Experiments on the accuracy of the proposed methods for the customized Pac-Man game show that the accuracy of the skill level was 1.2 grade as the difference on the average and the accuracy of the game difficulty level was 1.81 grade the difference on the average. The results show that the proposed methods are accurate enough to be applied to casual action games satisfying the zero-sum condition.

This study meta-analyzed the effect of 32 research papers on children in academic journals published with domestic degrees and gameplay Therapy programs (2004-2017). As a result, the total effect size was 0.971, a large effect size. The impact scale by variable factor of disabled children, ages 3 to 5 years by age, and the impact scale of psychological variables by dependent variable were reported, with 11 to 15 sessions per process, total number of sessions 16 times or more, session count per week, and session count 61 to 90 minutes. The biggest research is meaningful in that it is the first comprehensive and objective analysis of gameplay Therapy programs and is expected to be used as basic data in treatment design when performing gameplay Therapy programs on clinical sites.

This study aims at empiricallly designing method to increase player's play capability through determining of the relations of player's behavior pattern and emotion factors when having gameplay experiences in MMORPG. For modeling emotion factors on gameplay, Our preliminary studies are considered in the process of rule-based systems on cognitive science approach. These study estabilished game architecture process applied of player's cognitieve emotion reactions in specific situation of role playing games that have most noticeable interaction with players based on quest system. This approach is expected to extend instant responses, which can be controlled behind all of anti-main behavior pattern and main behavior pattern in game playing. Therefore, such study is meaningful that is proposed the analysis framework of player's emotion factors to design game playing capability in game interactions.

Research on the visual narrative impact of Unreal Engine's Lumen lighting system in games aims to delve into how Lumen's lighting technology plays a crucial role in game design and gameplay experience, thereby enhancing the visual storytelling of games. Lumen, Unreal Engine's dynamic global illumination solution, calculates lighting and shadows in real-time during gameplay, creating a more realistic and immersive environment. Analysis indicates that Lumen technology not only provides visually realistic and dynamic lighting effects but also significantly enriches the expressiveness and immersion of the game narrative through its changes in light and shadow.

The purpose of this study is to investigate the actual situation of the surrogate games and win trading gameplays in e-sports leagues, and to insist on the creation of new regulations to punish them. The surrogate game surveys was conducted for 40 amateur users and 17 professional users in e-sports leagues. The survey was conducted in-depth interviews with a professional user to learn more about the actual situation of the win trading gameplay. As a result of the study, professional users had a high rate of experience with Gahz'rilla, and they would be able to increase their game rankings through Gahz'rilla. But they did not think Gahz'rilla is a surrogate game. Amateur users had a low rate of experience with Gahz'rilla and did not think they would be able to increase their game rankings through Gahz'rilla relative to professional users. Amature users tend to think of Gahz'rilla as a surrogate game. Both the users agree on the necessity of regulation on Gahz'rilla and surrogate game. Therefore, it is necessary to narrow the gap between the professional users and the amateur users by establishing rules for Gahz'rilla and surrogate game.

Digital game is an entertainment content as well as a cultural content so that digital game can deliver social messages to make people confront with current problems. Based on Gonzalo Frasca's expanded model theory, this study aims to analyze independent games parodying reality on the level of the narrative and the gameplay to demonstrate that digital game can be a powerful medium to represent a satire on society. Parody games describe irrational side of society as being comical and provoke players' repetitive gameplay. Therefore, players can experience serious theme through casual play in the first-person, and realize the tragic reality directly.

A Human Computation Game(HCG) is designed to solve difficult problems that cannot be dealt with computers with a large number of individuals' voluntary participations. Most existing relative studies focus on building more efficient system for problem solving, or the individual cases on the development of certain HCGs. However, a game is fully completed by the players who play it. Therefore, additional research is needed to annalize the ludic elements of HCGs, which induce people to play them voluntarily. We studied the purposes, tasks, and the game mechanics of 31 HCGs, then suggested how to design more enjoyable HCGs.

Ludo-narrative dissonance is a prevalent problem among open-world genre video games. However, Ghost of Tsushima (2020) alleviates this issue by designing its characters and narrative structure influenced by Akira Kurosawa's samurai films. The game's protagonist represents "Bushido," a samurai code, and the structure exudes similarity to Joseph Campbell's "Hero's Journey," which heavily influenced Kurosawa's films. The developers also designed the gameplay mechanics such as level-up system, map design, and side quests based on these narrative traits, ultimately making the goal of the narrative and the gameplay mechanics cohesive.
