Scientists warn free-to-play games hide high costs, urging stronger player protections

Free-to-play videogames are not as “free” as they appear. A new study of adolescents finds that a small minority of players accounts for most spending on in-game purchases, while also showing higher rates of symptoms associated with gaming disorder and gambling disorder. The findings suggest that the economics of modern videogames may be relying disproportionately on players who are more vulnerable to losing control over their time and money. Researchers Markus Meschik and Mark Griffiths argue that consumer protection should therefore focus not only on loot boxes, but on the wider architecture of digital monetization.

The free-to-play model has transformed the videogame industry. Instead of paying an upfront price, players can download and begin playing at no cost. Revenue is generated through microtransactions, which may unlock cosmetic items, accelerate progress, provide access to premium content or allow players to participate in limited-time events. Although these purchases are formally voluntary, the word “microtransaction” can obscure their potential scale. Individual payments may reach €100 or more, while repeated smaller payments can accumulate rapidly over weeks or months. The financial impact is especially significant for children and adolescents, who may have limited income and less experience managing persuasive commercial environments.

The study’s central finding concerns the distribution of spending. Rather than being evenly spread across the player population, expenditure was heavily concentrated among the highest-spending 10 percent. This group, described by the researchers as “heavy spenders,” generated the majority of all money spent on microtransactions. The investigators avoided the gambling term “whales,” which is commonly used for customers who spend unusually large amounts, because they wanted to describe the pattern without importing assumptions from the gambling industry. Nevertheless, the statistical shape of spending was strikingly similar to the inequality observed in gambling, where a relatively small group often contributes a disproportionately large share of total revenue.

This concentration matters because averages can make risky behavior disappear. If most players spend little or nothing, the average amount spent across all users may appear modest even when a small number of players are spending very large sums. In economic terms, the distribution is highly skewed: a long tail of low-spending or non-spending players is accompanied by a much smaller group with substantially higher expenditure. A median value, which identifies the middle player, can also conceal the upper end of the distribution. For regulators and public-health researchers, examining percentiles and spending inequality is therefore more informative than relying on a single average.

The researchers also examined the relationship between spending and problematic behavior. Heavy spenders were more likely to report indicators associated with gaming disorder and gambling disorder than players who spent less. Gaming disorder generally refers to persistent or recurrent gaming that becomes difficult to control and continues despite negative consequences, such as conflict, impaired functioning or loss of interest in other activities. Gambling disorder involves persistent problems controlling gambling and continued participation despite harm. The study does not establish that microtransactions caused either condition. Because the research used survey data, it can identify associations but cannot determine whether problematic behavior leads to heavy spending, whether spending systems intensify existing vulnerabilities, or whether both are influenced by other factors.

The overlap with gambling is not limited to loot boxes. Loot boxes involve purchasing a randomized package of virtual items without knowing exactly what it contains, a mechanism that has been compared with gambling because the buyer pays for an uncertain outcome. Modern games also use battle passes, virtual currencies, rotating shops, paid progression, personalized offers and time-limited events. These systems can operate together to increase purchase frequency and urgency. A player may first exchange real money for a virtual currency, reducing the psychological salience of the price, and then encounter a limited-time offer or countdown that encourages an immediate decision. Personalized promotions can further tailor prices, rewards or messages to individual patterns of play and spending.

One technical concern is event frequency, a concept widely studied in gambling research. When opportunities to spend occur repeatedly and with little delay between decisions, the cycle of cue, purchase and reward can become highly regular. In videogames, the transaction may take place with a few taps, while the reward appears immediately on the screen. This compressed sequence reduces the time available for reflection and can make individual payments feel disconnected from their cumulative cost. The researchers propose introducing “friction”—deliberate interruptions such as confirmation delays, spending summaries, cooling-off periods, transaction limits or clearer conversion of virtual currency into real-world prices. Such measures would not necessarily prohibit purchases, but could reduce their immediacy and regularity.

The findings arrive as policymakers are increasingly examining digital platforms for design practices that steer users toward decisions benefiting providers. These practices, often called dark patterns, may include confusing interfaces, default settings, social pressure, scarcity messages and difficult cancellation procedures. Videogames remain less strictly regulated than gambling in many jurisdictions, even when their monetization systems use comparable psychological mechanisms. Belgium and the Netherlands have attempted to address loot boxes through national rules and enforcement, but research has suggested that regulating one mechanic at a time may have limited effectiveness. Developers can alter the presentation of a system without removing the broader incentives that encourage repeated spending.

Children and adolescents may require particular protection because they are still developing financial judgment, impulse control and the ability to recognize persuasive design. The study found that heavy spending was not confined to young people from affluent households, challenging the assumption that high expenditure is simply a harmless luxury available to wealthy families. Parents and caregivers are often expected to monitor accounts and restrict purchases, but this responsibility can be difficult to carry out when games are designed to maximize engagement, personalize offers and make transactions seamless. Parental controls may help, but they do not address every mechanism that encourages spending or the social pressure to remain competitive within a game.

The researchers emphasize that most people play videogames without developing serious problems, and the existence of heavy spenders does not mean that all free-to-play games are harmful. The public-health issue is instead one of disproportionate risk: if a small minority generates most of the revenue, that minority deserves closer scrutiny than the average player. The study, published in Frontiers in Public Health, supports a broader assessment of monetization systems that considers spending distributions, purchase frequency, behavioral vulnerability and the cumulative effect of multiple design features. Its message is straightforward: a game can be free to download while still creating powerful commercial pressures, and protecting players will require regulators to examine the entire spending environment rather than focusing on a single controversial feature.
