forced screening and classification of the games

Paper instructions:
Assume you are the owner/manager of a video game production studio, and a powerful entertainment group filed legal action against your business in an attempt to force you to submit your games to a special board that would decide to whom your outlets could market the games. And as a result of the forced screening, your games would be rated using the same system as the Motion Picture Association of America for audience classification of films. Your games are animated using no live actors and contain notices concerning the graphic nature of the contents along with a recommendation for parents of minors purchasing the games.

Discuss your argument for and against the forced screening and classification of the games and any Constitutional grounds you may believe apply. How do your responses fit with a free market based economy?
