However, I can understand the need to restrict the access of inappropriate materials by children. And in this instance, I think that the best methods of doing this is self regulation by the industry, increasing information about game ratings, and getting retailers to enforce these restrictions.
As I have ranted before, the sales of inappropriate video games to minors often continues due to either 1) parents buy these games for their children without knowing that they are, and 2) retailers selling them to said children.
The Electronic Software Ratings Board has done a fairly good job on accurately rating these games, and parents have a good amount of information to base their purchases on. And they have just created a widget that can be added to any website or blog, giving users the tools to check out the ratings on any game. I have added this widget to my page, because I feel that I share the responsibility in helping to highlight the available information.
If you're a gamer, I hope you feel the same way too.
