Hey C023!

I think it can help people understand your intended audience better; especially if it's not immediately obvious. If you game looks like a comic, for example, but it contains mature matter (think - Family guy, for example) - putting an intended audience can help.

As far as I understand it, the ESRB does not currently censor online/digital content, so unlike on consoles and on retail products, you are not technically legally required to get your game rated before release (if anyone knows differently, please correct me!).
