A Large-scale Friend Suggestion Architecture

Online social as an extension of traditional life plays an important role in our daily lives. Users often seek out new friends that have significant similarities such as interests and habits, motivating us to exploit such online information to suggest friends to users. In this work, we focus on friend suggestion in online game platforms because in-game social quality significantly correlates with player engagement, determining game experience. Unlike a typical recommendation system that depends on item-user interactions, in our setting, user-user interactions do not depend on each other. Meanwhile, user preferences change rapidly due to fast changing game environment. There has been little work on designing friend suggestion when facing these difficulties, and for the first time we aim to tackle this in large scale online games. Motivated by the fast changing online game environment, we formulate this problem as friend ranking by modeling the evolution of similarity among users, exploiting the long-term and short-term feature of users in games. Our experiments on large-scale game datasets with several million users demonstrate that our proposed model achieves superior performance over other competing baselines

Loot Box Purchase Decisions in Digital Business Models: The Role of Certainty and Loss Experience

Game providers are increasingly employing and selling loot boxes, which can be considered virtual goods that consist of further virtual goods on a randomized basis. As such, game providers can foster profitability without impeding user experience. Drawing on prospect theory, we investigate ideas for the design of loot box menus to optimize revenue generation and user well-being. By conducting a contest-based online experiment with 159 participants, our analyses reveal that including certain (vs. uncertain) content in loot boxes can influence users’ purchase behaviors and thus increase revenues. Moreover, this effect increases when participants previously experienced a loss. Thus, our findings demonstrate that game providers can profit from offering certain content in loot boxes

Ingress Well-Played: City as MMO

This paper describes player experience for Ingress, a geo-local, mobile augmented reality game created by Google’s Niantic Labs. Ingress incorporates aspects of both pervasive, alternate reality (ARG) and massively multiplayer online (MMO) games. However, unlike many ARGs, Ingress is not focused on a specific time-limited period, or linked to a single real-world event or location. And unlike a typical MMO, play in Ingress is geo-spatially limited; players must be physically proximate to game elements in order to interact with them. Using game mechanics similar to those of many MMOs, Ingress provides for a range of gameplay, based both on user play preferences and level of experience and achievement. with a focus on the importance of social, community, and collaborative aspects of the game

Putra BINGO : from pen and paper to digital

Gamification is one of the trends in education that is best suited to the current learning environment. Putra BINGO is a transformative assessment tool that uses gamification techniques. This research starts by elaborating the concept of Putra BINGO and its implementation using traditional method with pen and paper. The feedbacks gathered from the implementation are analyzed and applied to develop a multiplayer educational online game using Unity Game Engine. This paper describes details of the development for its two components; the database and the digital online game. Putra Bingo is available on PC and Android devices. It required additional plugins such as Photon Networking to handle game communication between multiple players. This is crucial to accommodate its test case application as an alternative assessment for teamwork skills using Rubrics and questionnaires. Further research will be conducted to enhance its functionality and user experience after the initial development of the digital online version is completed

Effect of cooperation on players\u27 immersion and enjoyment

This research examines the effect of cooperative versus non-cooperative game play on immersion and enjoyment in online games. It draws on the self-determination theory to generate the research hypotheses and explain the observed phenomenon. A within-subject experimental design (N=38) was used to evaluate the effects of cooperative versus non-cooperative game play on enjoyment and immersion by having participants play in a manipulated game mode in a controlled gaming environment. The participants\u27 subjective responses were assessed to understand their user experience in cooperative and non-cooperative gaming environments. The results suggest that both immersion and enjoyment were significantly enhanced in cooperative game play. --Abstract, page iii

Building Community and Collaboration Applications for MMOGs

Supporting collaborative activities among the online players are one of the major challenges in the area of Massively Multiplayer Online Games (MMOG), since they increase the richness of gaming experience and create more engaged communities. To this direction, our study has focused on the provision of services supporting and enhancing the players' in-game community and collaboration activities. We have designed and implemented innovative tools exploiting a game adaptation technology, namely, the In-game Graphical Insertion Technology (IGIT), which permits the addition of web-based applications without any need from the game developers to modify the game at all, nor from the game players to change their game installation. The developed tools follow a design adapted to the MMOG players' needs and are based on the latest advances on Web 2.0 technology. Their provision is performed through the core element of our system, which is the so-called Community Network Game (CNG) Server. One of the important features provided by the implemented system's underlying framework is the utilization of enhanced Peer-to-Peer (P2P) technology for the distribution of user-generated live video streams. In this paper, we focus on the architecture of the CNG Server as well as on the design and implementation of the online community and collaboration tools
