In free-to-play (F2P) games, development has rapidly progressed in recent years with the introduction of numerous new games as well as new revenue models. In 2014, a survey was conducted to understand how game developers themselves viewed the genre and its revenue models, but since then, there have been changes in the F2P model and the gaming industry. This survey aims to again examine how developers currently perceive the model and its evolution in recent years. Among players, there has been a perceived sense of unfairness regarding the F2P model, and the revenue models have been perceived as intrusive and aggressive. Some of these revenue models have also been linked to problematic gaming behavior due to their design. The research question underlying this study is: How do game developers view the current in-app purchase (IAP) model in mobile games? Is it possible to design it in a way that is not perceived as intrusive and unfair, while still serving as a viable revenue model for companies? To answer this question, the study employed a qualitative approach, conducting several semi-structured interviews with individuals working in the gaming industry. The interviews were then subjected to thematic analysis to identify codes and themes. The results indicate that developers generally have a positive attitude towards the F2P model. However, they do see issues with how some of the revenue models are implemented and presented to players. The interviewees expressed optimism about the future of F2P games, but they also believe that the revenue models may undergo changes.
