Concerns about materialism among children are strengthening. Media, especially television and advertising, are acknowledged to be an extensive channel that promotes materialism. Recently, dress up role-playing games, which are mushrooming in online space and mostly played by girls and female adolescents, facilitate active experiences of bountiful consumption simulations. The present study identifies the influence of dress up games on socializing materialism in children. Based on a survey of 144 young girls aged 7 to 13 in Semarang, Indonesia, the findings indicate that the frequency of dress up gameplay influences children to become materialistic. However, the effect of dress up gameplay is not significant when age and motivation to play are included in the analysis.
