A library in Mount Prospect, Illinois launched a Halo 2 event to attract more children, but controversy has followed in the wake of the decision.
The game bears an "M for Mature" rating, delivered by the industry's own ESRB. In light of the rating, the library has asked participating youth to bring permission slips signed by their parents.
That move has not appeased David Walsh of the National Institute on Media and the Family, which is based in Minnesota. "I think it borders on irresponsibility to sponsor an activity for kids as young as 12 that the industry itself has said is for adults," he said.
