Abstract
The purpose of this study is to investigate and conceptualize the relationship between pricing model sand motivations for MMO play. After are view of previous studies, we conducted empirical research in the Japanese MMO industry to find determinants of pricing models.
As a result, we found (1) a relationship between monthly fixed fees, continuous play (play periods) and social motivation, and (2) a relationship between per-item biling, relatively short play periods and high immersion.
