This study aims to empirically prove that blockchain games can provide business model innovations through interoperability among NFT based game items. Through our research on 'PlayDapp platform', we figured out that the technological innovation of blockchain games not only has provided a positive influence to the socio-economic and industrial ecosystem perspectives, but also it differentiates companies(game developers and platform providers in this eco-system) and increases customer benefits.

In this paper, we study and develop content for a puzzle game that can be enjoyed lightly with appropriate rules us ing Chilgyo-Nori blocks and Tetris blocks. We plan and develop puzzle games with low entry barriers and high revisit rates from the perspective of client indie game developers who are away from mass-produced games that additionally r equire specific items in a specific game section by focusing on the commercialization of game contents. The implement ed game promotes the creativity of users based on the possibility of creating more 2D designs than the existing Chilgy o-nori by using the Tetris block and the Chilgyo-nori block at the same time.

This study is discussed research on management of items in PC's GUI(Graphical User Interface) environment. A items are general knowledge data like books, musical CD, English CD, and game CD, which are the time when we don't seek the right items in the case of re-reading and re-listening the items. In this paper, We propose an example designed to be used in the management of a items. The proposed example is implemented by educational VC＋＋(Visual C＋＋) programming language. This program and discussions for management of a items will understand the development procedure of searching and storing data, which will provide some basics into designing large database systems.

The multimedia data of game affects the immersion of the game depending on its quality. It is difficult to design the evaluation criteria of artistic quality of the data. But, in a technical point of view, it is possible to evaluate its quality. Thus, the design of evaluation standard can ensure the reliability and objectivity of quality. However, multimedia data quality evaluation metrics had not yet been designed. Therefore, in this study, we extracted quality evaluation elements of Game Multimedia Data, and verified the reliability of the elements. And we defined detailed evaluation items of each element, developed Multimedia Data Quality Evaluation Metrics. We expect that the results of this study will serve as a guide in the development of high-quality games, have a positive impact on the growth of the game industry.

This study analyzes the system of Loot Box in Overwatch, FPS genre game produced by an American company Blizzard. Currently, one of the most controversial issues in the recent industry is "Probability-Type Item" that game users purchase high-end game items as a form of lottery. As this study examines a foreign case of Loot Box that is similar to Probability-Type Item, it would show how it is constructed and does legal approaches. Throughout this, it not only analyzes pros and cons of the Loot Box system, but also provides thought-provoking messages for the issue of the Probability-Type Item.

This study investigated player responses to microtransactions in freemium Massively multiplayer online roleplaying games (MMORPG), specifically focusing on the game LostArk using English language review data. To this end, structural topic modeling was employed and the following six microtransaction-relevant topics were identified: microtransactions, developer issues, real money trade (RMT), random number generator (RNG) upgrade system, game content, and collectibles & adventure. The first four topics were classified as being "not recommended". However, the proportions of microtransaction-related topics were relatively lower than the other topics. Additionally, this study did not extract keywords related to unfairness and unethical issues in previous microtransaction research. The last two topics, game content, and collectibles & adventure were "recommended" topics, indicating positive functions of microtransactions such as enhancing the game experience by purchasing virtual items. Moreover, it was found that players who do not engage in microtransactions can still be satisfied through continuous game content updates. Additionally, an examination of the interaction effect between time and recommendation status revealed that while the frequency with which the six microtransaction-related topics were mentioned increased over time in the reviews, the ratio of recommendations to non-recommendations varied differently. This study contributes to game-related research by revealing players' authentic opinions on microtransactions in freemium MMORPGs, thereby providing practical implications for game companies.

The purpose of this study was to evaluate the usability of a hybrid mobile reading game among 14 parents of children with reading disabilities. The reading game consisted of six steps according to the process of reading (familiarizing with consonants and vowels, acquiring whole words, combining consonants and vowels, reading words, phonological rules, reading fluency). In this study, parents experienced steps one through three of the reading-game app and evaluated the general design features and Universal Design for Learning on a five-point scale. Regarding the general design features, parents rated usability (18 items in total) as high in the following order: interactive design, instructional design, and interface design. Regarding the Universal Design for Learning (9 items in total), parents evaluated usability as high in the following order: providing multiple means of representation, providing multiple means of action and expression, and providing multiple means of engagement. Lastly, suggestions for the improvement of the app, practical implications, and suggestions for future research are discussed.

Recently, HTML5 have drawn many people's attention since it is considered as a next-generation web standard and can implement a lot of graphic and multimedia-related techniques on a web browser without installing programs separately. In this paper, we implement a game independent of platforms, such as iOS and Android, using the HTML5 canvas. In the game, the main character can move up, down, left, and right not to collide with neighboring enemies. If the character collides with an enemy, the HP (hit point) gauge bar reduces. On the other hand, if the character obtains heart items, the gauge bar increases. In the future, we will add various items to the game and will diversify its user interfaces by applying computer vision techniques such as various gesture recognition.

We have developed a serious game for the elderly named 'Paldokangsan3' as a next version of 'Paldokangsan2' which was a walking game with memorization in shopping streets using controllers of hand buttons and foot boards with PC developed in 2012. The interface of had buttons and food boards were changed into the interface of motion capture with the aid of Kinect. The expected effects are improvement of memorization, improvement of concentration ability to find out items in the vision, improvement of vitality through physical walking actions, as well as improvement of mental health through entertainment activities of game play. We have tested 25 volunteers of more than 65 years old in Cheonan city community center for the elderly for 2 weeks. We got the result that the game play was showing positive effectiveness on memorization, physical exercise and self-esteem in mental health area of the elderly.
