prices
As long as they're "part of the game" and unintrusive, I think I could just about live with it. Billboards adoring the course of a racing game are "normal", if they were dynamic they probably wouldn't disturb you any more or less. However, if they aren't in some way passing back the profits to the customer, IE by shaving a few quid off game prices (which, of course, I'm _sure_ they will *cough*) then they can get royally bent!
