Game Politics has referenced an interesting piece about a Virginia bill that would require three by three inch boxes for video game ratings information. The image avove is taken from the article, comparing the current differences between how ratings are displayed on games and on DVD movies. The game on the left is San Andreas. On the right is Shaun of the Dead. Interesting difference, no? The Virginia bill would require that the space reserved for ratings be even larger. As far as I know, no language in the bill asks to make movie ratings more prevalent.
