In this paper, we investigated the approach of advertisement to game users. The interaction area in the game was considered to be an effective advertising delivery area. In order to verify this, theoretical research was applied to the theory of advertising in game interaction. Then, based on the theory, we designed and produced the contents of the Gamification contents. The game was produced by being classified as exposed advertisement and interactive advertisement. Based on these two, professional focus test was conducted. As a result, we have verified the design of a Gamification advertisement applied to game interaction. The validity of the theory of Interactive Advertising Design was acknowledged. However, production verification proved to be below average.

Despite the increasing influence of the game, the general perception of the game is still negative. In addition, there is a lack of understanding of game users. Therefore, this study aimed to grasp the user's motivation factors related to the good use of the game and to understand the positive and negative effects of the game on the user's attitude. The results of this study can be used to improve understanding of game users in the future, strengthen the competitiveness of the game industry, and improve youth guidance.

This paper proposes a strategic portfolio model for managing performance of online games. The portfolio matrix is composed of two dimensions: financial performance and non-financial performance. Financial performance is measured by the conventional measure, average revenue per user (ARPU). In terms of non-financial performance, five non-financial key performance indicators (KPIs) that have been widely used in the online game industry are utilized: RU (Register User), VU (Visiting User), TS (Time Spent), ACU (Average Current User), MCU (Maximum Current User). Data envelopment analysis (DEA) is then employed to produce a single performance measure aggregating the five KPIs. DEA is a linear programming model for measuring the relative efficiency of decision making unit (DMUs) with multiple inputs and outputs. This study employs DEA as a tool for multiple criteria decision making (MCDM), in particular, the pure output model without inputs. Combining the two types of performance produces the online game portfolio matrix with four quadrants: Dark Horse, Stop Loss, Jack Pot, Luxury Goods. A case study of 39 online games provided by company 'N' is provided. The proposed portfolio model is expected to be fruitfully used for strategic decision making of online game companies.

Based on the love styles theory used in psychology, this paper classifies users(Passionate Love, Game-playing Love, Friendship Love, Practical Love, Possessive Love, Altruistic Love) and investigates satisfaction with the motivation for using TikTok love videos(Entertainment, Social Relationship, Love skills-learning, Self-verification, Problem-solving) according to the theory of use and satisfaction. First, 414 users were selected to conduct TikTok surveys to collect data. Then, through the analysis of the research results, among the six love types, game-playing type and possessive type have a positive (+) impact on entertainment motivation and love skill-learning motivation. Game-playing type also have a positive (+) impact on social relationship motivation and self-verification motivation. In addition, altruistic type and possessive type are also factors to strengthen the motivation of self-verification. The altruistic type, possessive type and practical type will improve the problem-solving motivation. Finally, through hierarchial multiple regression analysis, it is confirmed that game-playing love type, entertainment motivation, love skill-learning motivation and self-verification motivation can improve user satisfaction. The above results enrich the research of user classification as well as providing inspiration for improving the quality and communication efficiency of TikTok's video and enhancing user experience.

This study analyzed the competition among three game platforms, PC, Console and Mobile in aspect of user's gratifications using niche analysis. To do this, four gratification factors, 'transportability and accessibility', 'liveliness and variety', 'availability and economic feasibility', 'relationship', were assessed. To investigate competition level among three game platforms, niche breadth, niche overlap, competitive superiority of four gratification factors were analyzed. The results of niche analysis show that mobile platform appeared as a most competitive platform because it utilized diverse resources for game user gratification and had competitive superiority in 'transportability and accessibility' which appeared as most important factor determining user's gratification. However there was no game platform which had competitive superiority in all four gratification factors.

Since the players in online games seek fun, emotional aspects may be important factors in the pleasure-oriented information systems. This study attempted to verify the effects of characteristic factors of games (fun, challenge, compensation, and diversity) on emotion and customer satisfaction in game portal sites. The study established the research model on the foundation of precedent researches related to online games, emotion, and customer satisfaction. The study conducted online and offline survey on individuals with experiences in using online game portal sites. 206 samples were used to test the research hypotheses. By using Structural Equation Modeling, The study found the following results. First, it was revealed that characteristics of games had positive effects on emotion in game portal sites and indirect effects on user satisfaction. Second, the study analyzed the difference between low user group and high user group. It was revealed that the characteristics of games had positive effects on emotion in the low user group, but only challenge factor influenced on emotion in the high user group.

Screen climbing is a kind of screen sports. In screen climbing, the software program is executed in a computer system and climbing is progressed by the interaction between a climber and the content of the screen. We implemented a screen climbing game with the ancient cave exploration considering the development of children and the children's motivation to sports climbing. The content of the game is projected to the artificial climb wall and the interaction between a user and the game is done by a user's input of Kinect's depth data. The game is popular with the children in the children's exhibition event. There should be implemented more screen climbing game.
