Controversial topics

I've decided for my controversial topic to cover video games, specifically the controversies surrounding violence and content. I chose it because I've always been interested in Video Games and the controversies surrounding them. I know that people believe that Video Games breed violence, and the controversies surrounding the content of games themselves, like in M rated games. I want to read more about it and find out where all of the ideas grew from, and mostly just read more about peoples ideas.
