I was watching this Zoo Tycoon video and it is a more family friendly game and I wondered why games don't have extra bits as DLC that would bump up the age rating. You could still market and sell it to a wider audience to keep all involved happy then tweak it by changing a few things. For instance in this videos the buggies you drive around in could allow you to drive over people rather than being stopped. Or chuck a few kids in the rhino section.
I guess it would depend how expensive it would be to put these things in and it wouldn't really suit some games. But basically sell a game to more people to start of with at a lower age rating and then have simple things like blood and swearing as free DLC. More interesting random -even badly implemented due to time/money constraints- things akin to silly cheats out of the context of the game would be great. So publishers would not have to worry as much about their sales.
Does this sound like a good idea or something that could happen?
