So would it be possible for a game to run solely on advertising?(read OP before posting)

I agree i think that advertise can more then compensate the price it would be for us to buy a game one off. IT would be very interesting to see and would make the world feel very beleivable as well.

Hell fast food restaurants can do like GTA games do. Walk in and buy something and get your health replenished. Walk in to Burger King or whoever wants to advertise there restaurant in there.
