Two game industry groups are suing to overturn an Indianapolis law barring minors from certain coin-operated video games. The American Amusement Machine Association and the Amusement and Music Operators Association want a judge to grant a temporary restraining order the keep the law from going into effect on September 1. "We are on the edge of a slippery slope, and our industry has been forced to litigate to protect core constitutional rights," explained Amusement and Music Operators President Frank Seninsky. The Indianapolis law allows coin-operated games featuring graphic violence or sexual content to be played only by those over 18, and such machines must be affixed with warning labels and kept out of the view of minors. Indianapolis Mayor Bart Peterson, county prosecutor Scott Newman, and local police officials are named in the suit.
