Pay-to-Win (P2W) is a billing system that pays cash in-game and has a impact on results and it has been criticized by users. Research on the adolescent users and the effect of the P2W is insufficient. In this regard, this study compares the game billing in P2W and non-P2W based on self-esteem. As a result, systems showed the interaction effect on the game billing with the self-esteem. In the non-P2W, game billing increased when the self-esteem was high, whereas the billing increased rapidly as the self-esteem was low in the P2W.

The core price policy of on-line game marketing are FPP(Fixed Pre Paid model and PPU(Pay Per Use) model. These two models have been a on-line game company's billing system and a fundamental of MMORPG in Korea. However, they took root billing system only for first movers recently. In now, the market share of several first movers is exceeding 80%, late movers witch have same billing system cannot take part in pair competition. Even though in MMORPG, many games of late movers were favorably noticed by a lot of gamers during Evaluation. Test, a lot of companies are bankrupt before make business. Late Movers declare free game first thing, they maintain their existence and win over customers in on-line game market. And next, they guarantee item selling, give multiple experience value and game money, at last, induce their customers to pay service. As it makes trouble between pay user and free user, and it linked up with the collapse of game contents balance that designed for FPP billing system, And then meet unexpected result which reduction of game life cycle. In this Paper, we classified several contents services based on game contents, and suggested contents premium services which adopted low cost strategy lead to micro payment. we hope it will apply to late movers' new billing system in MMORPG.

ITU-T's NgN(Next generation Network) architecture is expected to offer a new Internet platforms such as QoS(Quality of Service) guaranteed services as it overcame the limitations of the existing best-effort Internet architecture. However, policy development crucial for the NgN framework(e.g., interconnections and billing) is lagging far behind technology development. For example, arguments over network neutrality clearly indicate little understanding of the Internet industry structure where diverse providers including ISP and CP coexist. This study employs a network economics approach to predict how the competitive landscape involving various providers will evolve under the traffic-based billing system under the NgN environment. Applied is the non-cooperative game theory, in particular, Stackelberg's repeated game in order to build and analyze model for competition among those providers. We also studied possible impacts that CPs would have on the competitive landscape if they have an option to replace ISP: i.e., CDN(Content Delivery Network) provider. Lastly, based on the model analysis and experiments, presented are their implications to policy development and tile future prospect.

The development and application of this monetization model is an important catalyst for the rapid growth and development of the smartphone game market. Therefore, we will examine the process of changing the monetization model of the entire game industry and the cultural characteristics of the micropayment model in Korea.

As the smart phone market is drastically expanding, there is a steady growth of recent vicious activities such as data manipulation, billing fraud, identity theft, and leakage of personal information that are security threats to Social Network Games(SNG). Due to the threats, Strong development standard is required for security enhancement of SNG. Nonetheless, short life-spans, additional expenses, and the necessities to provide a sound game service hinders developers from reaching their security goals. Therefore, this research investigates the weak points of SNG through memory manipulation experiments based on the currently provided SNG services. In addition, the research presents counter measures and security enforcements that are light in service load and simplistic which can be applied in the developing process.

Currently, the 'Gacha' system is becoming an indispensable profit generation method for online and mobile games. The system, also called "probability randomization," proceeds with cash-based payments, and it is not clear how much money you need to use to obtain the item you want. So, in response to the backlash of users, game companies introduced a "ceiling" system that allows users to get the items they want if they use it for more than a certain amount, and added several profit generation methods using it. We examine the impact of this system on continuous billing induction.
