I think that the possibility of having your own advertisements around the towns and villages etc, as it would create a huge opportunity for people to grow their businesses into what they want it to be. Something like a skyscraper, but on the side, you see a huge monitor which is showing your advert. The way I think adverts could be made, would be similar to how paintings are made, and how videos will be made. Basically, I think that there should be studios etc (or even player made work places) where players can make and edit videos for things like TV, adverts and even social media.
