Actually the in-game advertising doesn't have to be so intrusive as is being thought. Take RuneScape for example. They use in-game "billboards" that have the ads running on them full time. You don't hear them from afar but as you get closer their volume gets louder. You can simply just walk on by if you don't care about the ad. Also in-game advertising can be something as simple as a pepsi can on the tables or a coke machine in some of the rooms. Try not to think of it quite like television to where they have to stop the game for a 30-second break as there are many more options out there. I, for one, support this because I like the idea of good games costing me less. I'd be willing to put up with "real-world" items in-game.
