Classify players based on player relationship network in MMOG

The economy crisis swept all over the world in 2008, but theindustry of massive multi-player online game (MMOG) did pretty well through last year. The major reason of that should be the enormous growth of the game players and their payments. The interactive behaviors among those players in MMOG make up of a complex relationship network. Based on our study, the core players of relationship network influence the other players because of the interactive pattern of MMOG. We classify players based on degree distribution of the relationship network, and apply the methods to two types of MMOG with different payment patterns. Then we come to a conclusion that the game companies should pay more attention on the demand of the core players. Our study in this paper should be used to improve the current E-game system design and strategies.
