There's plenty of room for innovation in the mobile game ad space. I actually do like the strategy of making the ads part of an achievement system for the game. This would work especially well for localized ads. For example, if you reach a certain level on a game, get $2 off your sandwich at Subway. This allows for brand exposure and funnels people into the physical stores.
