Abstract:
In today's digital entertainment market, "Free-to-Play" has become a commonly used business model for many mainstream electronic games. Players can download and experience it with zero threshold, but then they will encounter an endless stream of in-app purchase options such as virtual props, level passes, and membership subscriptions.
A new academic study recently published in Frontiers in Public Health pointed out that this model seems harmless to most people, but in fact it transfers a huge financial burden to a small group of vulnerable players who are susceptible to addiction, and its revenue polarization characteristics are surprisingly similar to the gambling industry.

This study jointly conducted by scholars from many countries shows that in-game purchases known as "microtransactions" are not really just "small money." In many games, a single top-up amount can reach 100 euros (approximately $117) or more, which is no small amount for children and teenagers. More importantly, the total revenue of game manufacturers is highly dependent on a very small number of high-spending consumers. Data shows that the top 10% of “heavy consumers” (often referred to as “big whales”) by spending amount contribute the vast majority of in-app purchase revenue. This unequal structure of spending, where a few people pay and most people get free, is almost exactly the same as the consumption distribution in the gambling industry.
Further investigation found that these heavy consumers do not necessarily come from wealthy families. On the contrary, gaming disorder (game addiction), gambling disorder and other impulse control problems are particularly high in this group. The research team points out that when a product generates the majority of its revenue from vulnerable groups prone to addictive behavior, the product's business logic must be subject to greater public scrutiny. Just because ordinary players only spent a small amount of money and suffered no obvious harm, it cannot be concluded that this profit model is safe.
In the past, the attention of regulatory agencies and the public mainly focused on the "Loot Boxes" mechanism with a random lottery nature, and compared it with traditional gambling. Some European countries have also introduced legislation to restrict it. However, researchers stress that loot boxes are just the tip of the free-to-play economy. Modern games generally adopt more subtle "Dark Patterns" designs, including battle passes, limited-time rotating stores, paid accelerated progress, personalized pop-up promotions, and virtual token systems. By setting token compartments such as "gems" or "gold coins" between real money and product prices, the game blurs players' perception of real spending; while countdowns and limited-time special offers artificially create a sense of urgency, prompting players to make impulsive purchases at the moment when they are most emotionally invested.
In view of this situation, researchers call on the regulatory system to move away from the narrow perspective of "only focusing on unboxing". Gambling research has confirmed that the frequency with which a behavior occurs is one of the strongest indicators of its addictive potential; in a game, the faster microtransactions are performed and the smoother repeated purchases are, the higher the chance that a momentary impulse will turn into long-lasting out-of-control behavior. At present, most of the supervision responsibilities are pushed to the parents of minors, but ordinary families are often unable to guard against the manufacturers' elaborate induction algorithms.
In order to curb irrational consumption, the study recommends introducing more "resistance" mechanisms in the payment process, such as mandatory consumption ceilings, unified use of legal currency pricing, increased purchase cooling-off periods and multiple confirmation steps, etc., in order to cut off the chain of automatic or impulsive transactions. Scholars pointed out that as online game monetization methods become increasingly sophisticated and complex, relevant legal and regulatory protections must be upgraded simultaneously. Those groups that are most likely to lose the ability to control themselves should never be allowed to become the biggest victims of free games to maintain commercial operations.
