A father in China has filed a video game addiction lawsuit against four major publishers, asking for just 10 yuan, about $1.50, after alleging their safeguards failed to stop his son from playing excessively.

The man, identified only by his surname Qin, brought the case in Tanghe County, Henan province. He is suing Tencent, NetEase, miHoYo, and 37 Interactive Entertainment.

The token compensation is deliberate. Qin says the case is not really about money, which the requested sum makes reasonably clear. He wants the court to push gaming companies to enforce protections intended to limit how long minors can play.
