From Play to Pay: How Game Design Elements Influence Players’ Microtransaction Intentions

In the Free-to-Play (F2P) game market, game design is pivotal for shaping player retention and driving microtransaction intention. This study integrates the MDA (Mechanics, Dynamics, Aesthetics) framework and Self-Determination Theory (SDT) to investigate how perceived game design elements influence players’ monetary behavior by satisfying psychological needs. An online survey was conducted with 362 Multiplayer Online Battle Arena (MOBA) players in China. The results reveal a nuanced mapping between design and motivation. Dynamic elements primarily foster competence and autonomy, while Aesthetic elements are key drivers of relatedness. Furthermore, autonomy emerged as the strongest predictor of microtransaction intention, highlighting the role of volition in non-functional consumption. Crucially, the study identifies divergent social mechanisms regarding co-player relationships. Playing with friends amplifies the impact of competence driven by status affirmation, whereas playing with strangers strengthens the impact of relatedness, which is driven by the need for swift trust. These findings operationalize MDA into a player-centric empirical model and offer actionable strategies for developers, such as designing achievement-gated virtual items for strong ties and thematic skins for weak ties.
