An AI would be able to detect bugs in a game video, i.e., frames in a play video that are more likely to have bugs, instead of human debuggers, by inputting “bug text’’ that represents in-video bugs as well as each frame of the play video and calculating the similarity of OpenAI’s CLIP between language and images. However, the existing studies for CLIPbased bug detection have a problem that they require to be input bug text manually. Therefore, this paper prototypes and validates a method to generate “bug text” as an input to CLIP along with each frame of the play video, by using object detection, WordNet, and ConceptNet, where bugs means that objects in a game video violate the laws of physics.

Procedural content generation is used in various places in game development, and helps to reduce the labor required in the development process. Evolutionary algorithms are being promoted as a method for automatically generating diverse dungeons. However, there is a problem that the amount of calculation required to generate enemies in the dungeon is large, and it is difficult to converge to an optimal solution. In this study, we proposed a method for automatically generating dungeons using the evolutionary algorithm and Map-Elites according to new room types and enemy distribution information specified by user input.

Recent advancements in AI, driven by Large Language Models (LLMs) and diffusion -based generative models have significantly enhanced the field. These models produce creative outputs comparable to human creations, expanding possibilities for automated creativity. While generative AI is used in game development, research on integrating automatic dialogue and environment generation as core game elements is limited. This study constructs a game system with dynamic scene transitions in response to user input. Specifically, we develop an adventure game that defines scene transitions and generates natural sequences in user-character dialogues for personalized dialog to create comfortable user experience, offering a co-living experience with AI agents reflecting user preferences.

With advances in CV (Computer Vision) technology, CV-based cheat tools for FPS games are becoming pervasive. CV-based cheats are more difficult to be detected than cheats that read in-game memory because they use CV to get enemy player’s positions. This paper proposes a method of applying an adversarial patch to each enemy character to avoid YOLOv5-based cheats, and validate the effects of the proposed method on rate of avoiding YOLOv5-based object detection. In addition, this paper evaluates the visibility of pasting an adversarial patch to each enemy through a questionnaire survey.

In recent years, ”social games” had created a significant impact on the Japanese gaming market. Some of the titles have expanded overseas, and successful overseas expansion may help the growth of the game companies. For Japanese game developers, Taiwan’s gaming market could be a popular candidate for the “first step” of overseas expansion. This is because of several factors such as the similarities in the sub-culture (due to the number of imports of Japanese games, anime, and manga), the geography, and the size of Taiwan’s gaming market (along with its gaming population). This study will pick up and introduce some of the Japanese social games that have entered Taiwan. This study will also conduct online surveys and interviews with local social game players. By examining social games through collecting voices of local game players, this presentation will find the diversities of the flow lines of Taiwanese game players, along with the limitations and challenges of overseas game management, along with solutions to some of the limitations.

This paper presents an analysis of audience and prize money data for eSports game titles from 2017 to 2022. eSports titles' audience numbers show the so-called scale-free nature of the results, while the prize money data has an exponential shape with prize money going to the top game titles. The data of total prize money has an exponential shape, where prize money is concentrated on the top game titles. A very small number of titles take the lion's share of viewers and prize money, and the top titles maintain their position over a long period of time. This confirms that this is a market where it is difficult for newcomers to enter.

Counter-Strike: Global Offensive (currently Counter-Strike 2) is a highly influential first-person shooter game that has captured the attention of many players and spectators. Providing accurate and timely information regarding in-game progress is essential for enhancing the spectator experience and for a deep understanding of player strategies. In this study, we focus on predicting the winning team of a round by frame information from a particular moment within the round. Additionally, we investigate the key feature values contributing to this prediction. We developed a range of features, such as player health points, equipment, and spatial distances between players, and utilized the XGBoost to predict the winning team. Our results demonstrate that factors like the difference in the number of surviving players of both teams, the ammo of specific weapons, and the proximity between players and the bomb play a crucial role in determining the outcome. Moreover, we observe that the significance of these features varies depending on the map.

This paper expands on C. Thi Nguyen's argument, which focuses on the process of striving for a game goals rather than the goals themselves, and considers the process that occurs when players want to clear the video games. In conclusion, it argues that the process in which the player analyzes and evaluates the abilities and environment given to them is important in video games. Furthermore, this paper suggests that players still engage in this process even in ”free” play, which Nguyen rejects as a way of playing game works.

Chinese mobile games currently wield significant influence worldwide. These mobile games not only represent Chinese culture but also portray the cultures of other countries, particularly Japanese culture. It is noteworthy that the representation of Japanese culture within these games is not an authentic depiction but rather a creation stemming from Chinese imagination—what can be termed as ”Chinese-style Japanese culture.” To elucidate this phenomenon, this paper will explore the representation of Japanese culture in Chinese mobile games, examining the causes and impacts from a multicultural critique perspective.

In recent years, there have been numerous attempts at serious games, and serious games for medical purposes are no exception. However, there have been few attempts at literature reviews, and it is difficult to say that there are sufficient systematic reviews. This study aims to investigate and examine the characteristics of medical serious games as a preliminary step for conducting a systematic review of medical serious games. As a result, there were 49 publications in 2022 and 53 in 2023 that contained both the phrase ”serious game” and the word ”medicine” in some field. While there was no concentration in the diseases, conditions, or medical fields targeted by these publications, it was found that literature in the field of medical education accounted for a certain proportion. Additionally, when using the same search keys, PubMed Central returned about 1,900 hits for publications from the past year, whereas PubMed returned about 80 hits. Furthermore, when the search keys were translated into Japanese and searched on CiNii (Citation Information by NII), the results were limited to fewer than 10 hits.

This case study is a presentation on the usefulness of home-made video games. There have been previous studies on medical serious games, in which hospitalized patients play serious games and become more positive about their treatment. On the other hand, there is a lack of previous research on the internal changes that occur when hospitalized patients develop own games. In this study, the first author, three hospitalized patients with muscular dystrophy and their occupational therapist (the second to fourth authors and the fifth author, respectively) formed a research team and jointly developed three types of games while sharing information online. The produced games were then exhibited at a community event and video recordings of the games being played were made available for reference. Finally, the co-researchers, hospitalized patients (second to fourth authors), were asked to reflect on their experiences through responses to a questionnaire. As a result, we observed an improvement in the inpatients' self-esteem through the experience of creating a game and having it played by able-bodied people.

The Japanese adjective ”omoshiroi” (interesting/fun) is polysemous and is frequently used to describe the appeal of video games. Although definitions for ”omoshiroi” exist in dictionaries and from linguistic perspectives, the context and nuances in which it is used remain ambiguous. In this study, we analyze the word embeddings of ”omoshiroi” and visualize similar terms through t-SNE dimensionality reduction and clustering. The results are presented using stereoscopic visualization techniques. By analyzing the words ”omoshiroi” and ”kawaii” (cute) with this system, several hypotheses regarding the meanings of these words were discovered.

Currently, there are various character development systems designed to attract player interest, but quantitative comparative analyses of their differences have not been sufficiently conducted. The purpose of this study is to elucidate the mechanisms of character development systems that keep players engaged. Specifically, we analyzed the skill acquisition trends common to three systems: skill trees, jobs, and monster development, and conducted a clustering analysis on parameter growth. It was found that by narrowing the units' areas of expertise and differentiating their roles towards the end of the game, player motivation is maintained. Additionally, the clustering analysis of parameters classified growth patterns into four categories. It was revealed that in the analyzed works, there are status improvement patterns specialized in agility, as well as patterns specialized in HP and attack, or special attack.

In poker, reading facial expressions and gestures is crucial for strategic gameplay. While some poker AI research incorporates player expressions for decision-making, the expressions of both players and the AI are often overlooked. This neglect compromises the traditional aspect of mutual expression reading. In this study, we propose an AI that not only makes decisions based on player expressions but also visually conveys its emotions through facial expressions and supplementary information according to game situations. This approach aims to facilitate bidirectional strategic interactions between humans and AI in poker.
