This page hosts a primary court document: the complaint in Antonetti v. Activision Blizzard, Inc., a federal video game addiction case that emphasizes alleged harm to the developing brain. Below is a plain-English summary, the causes of action, the key allegations transcribed, and the original PDF. It is part of our coverage of Video Game Addiction Lawsuits.

Case status:

Filed May 8, 2024 in the U.S. District Court for the Northern District of Georgia (No. 1:24-cv-02019-TWT), amid the same wave of federal video game addiction cases. The JPML declined to create a nationwide MDL in June 2024 (MDL No. 3109), and individual cases proceed in their home districts.

About this document:

This page reproduces and summarizes a civil complaint. A complaint is the filing that begins a lawsuit, and every statement in it is an unproven allegation made by the plaintiff. The defendants deny these allegations or have not yet responded in court, and nothing on this page is a finding that any company named did anything wrong. A complaint reflects only one side's account.

Plain-English Summary

This complaint was brought by Michael Antonetti against Activision Blizzard and a group of other game companies and platforms. Like the other cases in this group, it alleges that the companies designed their games to be addictive and failed to warn users — but it places particular emphasis on allegations that prolonged play causes physical harm to the brain, especially the developing brain of a minor.

The complaint alleges that the plaintiff played a long list of titles — including multiple Call of Duty games, Grand Theft Auto 5, Overwatch 2, Rainbow Six, Fortnite, and Minecraft — for roughly twelve hours a day, and that the plaintiff suffers alleged brain damage along with worsening ADHD and anxiety attributed to gaming.

The case was filed in May 2024, around the time the Judicial Panel on Multidistrict Litigation was deciding whether to consolidate these cases. The panel declined to do so in June 2024. See our Video Game Lawsuit Updates for current status.

Causes of Action

The complaint sets out the following claims. Each is an allegation the plaintiff would have to prove; listing them does not mean any has been established.

Key Allegations (Transcribed)

The text below is transcribed and condensed from the filing so the primary source is readable and searchable. The full 191-page complaint, including every numbered paragraph and count, is embedded below.

Transcribed from the complaint's Nature of the Action. These are the plaintiff's allegations.

The complaint alleges that "video game addiction, also called internet gaming disorder, is a condition characterized by severely reduced control over gaming habits and increasing priority given to gaming over other activities, resulting in negative consequences in many aspects of a person's life, including self-care, relationships, school, and work."

It alleges that the defendants "manufactured, published, marketed, and sold video games, gaming platforms, and/or gaming hardware" that they "had specifically developed and designed to cause the addiction experienced" by the plaintiff and other users, using "traditional game tactics such as feedback loops and reward systems, along with patented designs containing addictive features and technology to ensure its users keep playing longer and spending more on 'microtransactions' within the game."

The complaint further alleges that the defendants "design their games to keep consumers playing — and spending — by enlisting the help of behavioral psychologists and neuroscientists" and that, "by acquiring — and addicting — users when they are young," the defendants secure "their profit stream by ensuring future engagement and monetization as these young users age." It characterizes this as the use of "unfair, unconscionable, and deceptive trade practices and conduct that prioritizes gamer engagement and spending over gamer safety."

Emphasis on brain harm. This complaint adds that the defendants make their games addictive "in part, by encouraging long-term, extended game play despite knowledge that such extended play causes physical harm to the human brain — and particularly to a minor's developing brain," and alleges the defendants' conduct "proximately caused Plaintiff brain damage and gaming addiction."

The plaintiff. The complaint alleges the plaintiff plays numerous games "approximately 12 hours per day," including multiple Call of Duty titles, Grand Theft Auto 5, Overwatch 2, Rainbow Six, Fortnite, and Minecraft, and "has also been diagnosed with worsening Attention Deficit Hyperactivity Disorder ('ADHD') and Anxiety due to video game addiction," requiring "out-patient counseling and medication therapy."
