Gov. Jennifer Granholm signed legislation that would make it illegal to sell or rent adult-rated video games to those 17 and younger.
"These are not just harmless games. The child becomes the protagonist," Granholm said before signing the legislation Monday afternoon in Detroit.
Hal Halpin, president of the Interactive Entertainment Merchants Association, said the video game industry almost certainly will file a lawsuit. Federal courts have struck down video game bans approved by Washington State, Indianapolis and St. Louis County in Missouri, saying they encroached on the First Amendment.
"Generally speaking, we feel it's unfair to single out games as an art form and treat them differently from music and movies," Halpin said.
