The third-person side view game perspective of side-scrolling games makes playing such games a completely different gaming experience from other traditional games. Nowadays, many game elements are combined with each other, and horror and puzzle elements are often combined to appear in side-scrolling games, bringing players a unique gaming experience. In such games, players seem to be watching their own manipulation of characters. The performance is the same as a stage play, so how to let players better experience such a horror and puzzle-solving stage play through the design of the characters is a key point. However, it is often difficult to accurately classify only from game elements, so first of all, the author will explain the game division of the side scrolling horror puzzle game. After that, this article will analyze the character designs in the three works with high sales and good reputation on Steam, and then draw conclusions.

Outdoor play for young children can promote the development of physical development, emotional development, and creativity development. However, due to safety accidents that occur in outdoor play, outdoor play is not progressed sufficiently. In this paper, we have developed smart functional educational games for AR education which can be easily used in early childhood education. In order to maximize the educational effect of the developed game and to provide customized education on the field, we conducted a focus group interview with a group of in - service child care teachers in the game design stage. Through this, we developed a functional game with AR system and verified the educational effect.

A game player experiences gameplay that game designer sets in play space according to goal of a game. Player's experiential behaviors are affected by the space structure of game level and its arrangements. Therefore, it is an important process to understand and analyze the space structure of game level at the initial stage of game designing. In this paper, we was aimed to analyze the space structure and components of FPS game level based on space theory. To attain the objective, observation was carried out on a total of 204 levels in 3 different kinds of FPS games and the difference in the distribution of spatial composition factors by the goal of a game level was identified. As a result of the analysis, experiential behaviors in the play space show a clear difference according to the goal of the game level and the space structure that derives this is different.

Presence, flow, and arousal are interesting user experiences provided by video and people's demand for media which responds to personal interest is getting strong. This research compares video watching and game play by conducting a survey and measuring brain wave to find out the difference of those user experiences in the two media. As a result, all the three user experiences were proved to be significantly higher in game play than video watching. And those EEG frequencies which are known to be related to the state of flow were also measured higher scalp distribution of the game play group. Finally, presence, arousal, and EEG(${\alpha}$, ${\beta}$, ${\delta}$) were found to have influence on the flow state in game play. This research is intended to prove above relations by experiment and make a contribution to the theoretical and methodological improvement in the related area.

A quest system is one of the important parts in the MMORPG (Massive Multiplayer Online Role Playing Game) contents. Because of its complexity in combining various content components, quest reward design belongs to a complicated work in estimating quest reward levels correctly in the initial development stage. In this paper, we suggest a new quest reward design technique by considering optimal quest play paths. We model a quest reward problem as the TSP (Traveling Salesman Problem) and solve that by adopting genetic algorithms. With our system, game designers easily estimate the optimal quest play path and it can be useful in reducing the trial-errors in the initial quest design process.

Most of the match-3 puzzle games supports automatic play using the MCTS algorithm. However, implementing reinforcement learning agents is not an easy job because it requires both the knowledge of machine learning and the way of complex interactions within the development environment. This study proposes a method in which we can easily design reinforcement learning agents and implement game play agents by applying PPO(Proximal Policy Optimization) algorithms. And we could identify the performance was increased about 44% than the conventional method. The tools we used are the Unity 3D game engine and Unity ML SDK. The experimental result shows that agents became to learn game rules and make better strategic decisions as experiments go on. On average, the puzzle gameplay agents implemented in this study played puzzle games better than normal people. It is expected that the designed agent could be used to speed up the game level design process.

This paper focuses on how cognitive and emotional structures affect humans during long-term interaction. We design an interaction with a turn-based game, the Chopstick Game, in which two agents play with numbers using their fingers. While a human and a robot agent alternate turn, the human user applies herself to play the game and to learn new winning skills from the robot agent. Conventional valence and arousal space is applied to design emotional interaction. For the robotic system, we implement finger gesture recognition and emotional behaviors that are designed for three-dimensional virtual robot. In the experimental tests, the properness of the proposed schemes is verified and the effect of the emotional interaction is discussed.

Recently, almost games are using the 3D environment. Therefore, it required strongly that well-structured 3D engine or tools for development of some complicate 3D applications efficiently. In this paper, we design and implement a 3D engine (PLay engine) using the DirectX 9 SDK of the Microsoft corporation. The PLay engine has independent module structure, which has object oriented characteristics. and has not only 3D rendering functions but efficient algorithms. Moreover, we implement some tools what has compatibility with our engine for convenience. Therefore, it helps development of a 3D application easily and efficiently. We also describe each module with 2-layer structure, and each tool with compatible module, and make a simple game using PLay engine for testify.

With the rapid growth of recent smart phone technology, the interests for the design of online game in mobile computing environment are highly focussed on with great attention. Smart phone as a mobile terminal device, however, has many restrictions for implementing online mobile game since the limitation of relatively low performance of a processor, low resolution of GUI, small memory spaces, and short battery power. Therefore, most of games are very restricted on online and multi-play functions. In this paper, we design and implement mobile online game app in component based smart phone environment in order to take over these restrictions in mobile environment. Especially, the implemented mobile game is able to play online game among Wi-Fi based game server and another smart phone.

In a game, the visual environment element is a means of expressing the intention of the developer, and is mediums that enable the player to gain to play experience of interaction. In this paper, the player's reaction to the visual environmental elements of the adventure game was patterned with a collection and analysis process by empirical experiments. The data collected through the experiment were about 10,000, and as a result of the analysis, 24 types of player reaction patterns were found in total. This can be used as a guideline for game space design by matching the properties of visual environment elements and the reactions against players occurring in the game play process to examine the play experience.
