This came up elsewhere. I have my doubts about it but I don't believe the discussion will be harmful to the game or our community.
My own thoughts on this is to allow appropriate in-game locations to respond to user selection by bring up some kind of outside ordering system. Grubhub might work as that company is location-aware. I'm not sure how well that would work for non-U.S. locations.
Product placement I'm not so sure about. The experience City Of Heroes had with Nike didn't go well. It might have been badly planned and executed so it's not out of the question. The thing is that players come into games to escape the real world and some of its commercialization. Some kind of voluntary interaction that provides a service like I describe above is one thing, but forcing people to deal with such is quite another.
Edit: I've gotten so used to correcting City of Heroes to City of Titans that I'm doing it when the first name is appropriate!
