Roblox and Minecraft Lawsuit Says Developers ‘Weaponized’ Games To Drive Addiction and Excessive Spending

Video game designers hired licensed psychologists to help shape and manipulate player behavior, according to allegations raised in the lawsuit.

A lawsuit brought on behalf of a Kentucky teen alleges that modern video games have been intentionally designed to harm users, while increasing the developers’ profits.

The complaint (PDF) was filed by Shawna Goble, as next friend, on behalf of a minor named T.G., in the U.S. District Court for the Northern District of California on November 7, pursuing damages from Roblox Corporation, Microsoft Corporation, Mojang AB and other unknown entities named as defendants.

Roblox Corporation is the manufacturer of Roblox, while Microsoft is the current owner of Minecraft, which was originally developed by Mojang. Both Roblox and Minecraft are modern, interactive video games, which encourage users to create and play in worlds they design themselves.

However, both games have faced increasing scrutiny in recent years as they have been cited in a growing number of video game addiction lawsuits. The condition is described as a loss of control over gaming to the point that it begins to dominate a person’s life, causing them to neglect school, work, relationships and other responsibilities even as the behavior leads to repeated negative consequences.

Research has shown video game addiction can begin as early as elementary school, and can result in stress, aggressive behavior, loss of impulse control, depression, anxiety and other behavioral concerns, especially among children.

In addition to mental health and video game addiction concerns, Roblox has also been named as a defendant in a growing number of sexual exploitation lawsuits, which claim that that the platform has inadequate safety safeguards have allowed predators to engage in sextortion, explicit image exchange, and even in-person assaults, causing severe psychological harm to children and teens.

In her lawsuit, Goble claims that major video game companies, including Roblox and Microsoft, have intentionally “weaponized” their platforms by embedding design features that push users, especially minors, into excessive play and spending. The complaint says developers built these systems to exploit psychological vulnerabilities through behavioral tracking, reward loops and algorithmic feedback that keep players constantly engaged.

According to the filing, both Roblox and Minecraft use “dark patterns,” or deceptive design tactics, meant to prolong gameplay and prompt in-game purchases. The companies allegedly hired behavioral scientists and licensed psychologists to refine these features, fully aware they could spark dopamine-driven reactions similar to gambling addiction. These tools, such as variable rewards, time-limited offers and social pressures, are said to prey on children’s developing brains, fueling compulsive play and repeated microtransactions.

In addition, the lawsuit argues that the games function more like conditioning systems than entertainment products. Through data-driven personalization and monetization tools such as loot boxes and battle passes, Goble contends, the defendants have built ecosystems designed to maximize profit rather than user well-being.

The complaint also points to the use of advanced data analytics to target players most vulnerable to addiction. By customizing gameplay and in-app offers to match each user’s behavior, Goble says, the companies have blurred the boundary between engagement and manipulation, all while marketing the games as safe, family-friendly spaces.

“Modern video games that are the subject of this litigation are not traditional arcadestyle video games. Instead, the video game products subject to this litigation are created with ‘operant conditioning’ to weaponize a video game for the unethical, reckless, and/or negligent application of this psychological technique to encourage a negative response as to the gamer and the positive outcome of increased revenue for the defendants.”

Goble’s complaint raises allegations of strict product liability, design defect, failure to warn, negligence, negligent failure to warn, intentional misrepresentation, negligent misrepresentation and fraud. 

Video Game Addiction Lawsuits Update November 2025

Last month, the U.S. Judicial Panel on Multidistrict Litigation (JPML) agreed to hear oral arguments on December 4, to determine whether all federal video game addiction lawsuits should be consolidated before a single federal judge.

This marks the second time in less than two years that the JPML has been asked to centralize video game addiction lawsuits. The panel previously rejected a 2024 request to combine cases involving more than two dozen companies and games, finding the litigation too broad and varied to justify coordination.

In the new motion, plaintiffs narrowed their focus to three titles, Epic Games’ Fortnite, Roblox and Minecraft, which they describe as “gateway” games that pioneered addictive design targeting children. At least 17 lawsuits involving those games are now pending in seven different federal districts.

If the JPML grants consolidation, all existing and future cases against the three developers would be transferred to a single federal judge for coordinated pretrial proceedings, including discovery, motions and potential bellwether trials to gauge how juries might respond to the claims.
