Design of an in-game economic system based on virtual currency and its impact on player behavior

The design of the in-game economic system is key to ensuring the balance and sustainability of the game. In this paper, each virtual currency element in the designed economic system is introduced in detail, and based on the PIPE network, the economic system model within the game is designed. A multi-faceted recognition assessment research of this paper’s system is conducted through a questionnaire. It was applied to five games to analyze the players’ game behaviors, and using regression models, the players’ behaviors were predicted using this paper’s system. Players’ overall recognition of this paper’s system is high, with ratings ranging from 4.09 to 4.66. Under the system of this paper, the amount of player’s income from selling game props is higher than the amount spent by buyers, such as in Game 5, where the difference between the two is $120.06. When players have a sufficient amount of virtual currency, the percentage of players’ time in the economic system is significantly higher. All the key factors in the system have different degrees of positive influence on players’ spending behavior.
