Dunn v. Activision Blizzard: Video Game Addiction Complaint
Last updated: June 25, 2026
This page hosts a primary court document: the complaint in Dunn v. Activision Blizzard, Inc., the lead action in the petition that asked the federal courts to create a nationwide video game addiction MDL. 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.
Filed November 3, 2023 in the U.S. District Court for the Eastern District of Arkansas (No. 3:23-cv-00224-JM). Dunn was the lead action in the petition to create a nationwide MDL. On June 5, 2024 the Judicial Panel on Multidistrict Litigation denied centralization (MDL No. 3109), so the case proceeds individually.
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 is the complaint that opened the Dunn case, brought by Casey and Thomas Dunn on behalf of their child, G.D., against Activision Blizzard and a group of other video game companies and platforms. The complaint alleges that the companies deliberately designed their games to be addictive to minors in order to drive engagement and in-game spending, and that they failed to warn families about those risks.
According to the order from the Judicial Panel on Multidistrict Litigation, the games at issue in Dunn include Battlefield, Call of Duty, Fortnite, and Rainbow Six. The complaint alleges that G.D. developed a gaming addiction with real-world consequences, including effects on school and family relationships, and that G.D. was diagnosed with ADHD and dyslexia.
Dunn is significant because it was the lead action in the petition asking the federal courts to consolidate the video game addiction cases nationwide. That petition was denied in June 2024. For the order itself, see our page on the MDL No. 3109 order.

Key Allegations (Transcribed)
The text below is transcribed and condensed from the filing so the primary source is readable and searchable. The full 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."
The plaintiff. The complaint alleges that G.D., a minor, "specifically has experienced severe emotional distress, physical injuries, diminished social interactions, a drop in grades and inability to attend school, depression, lack of interest in other hobbies and sports, withdrawal symptoms such as rage, anger, and physical outburst, and diagnoses of ADHD and Dyslexia," and that G.D. "required an Individualized Educational Plan ('IEP'), out-patient counseling, and Focalin medication to control impulsivity and lack of control."
