As long as they fit into the game fine. For example one of those old coke ads, no neon light Coke signs in a WW2 game. Anyways I will never buy a $60 game.
I don’t mind crafty product placement, but I don’t want to see ads. They don’t even affect my buying decisions, I rely more on what my friends say than I do a commercial. I have never bought something because I saw the ad, I think it is silly and a waste of time and money.
