We are developing an iPhone/iPad game that is going to be something similar to Gunbound for PC and will introduce some all new game mechanics that have never before been seen in the App store. It's super exciting, and we're stoked on it! (We are aiming for a v. 1.0 release this December so stay tuned!!) We are investigating how to make this game profitable, and looking at having in game advertising. The idea is attractive since potentially over time a single download of an app could make far more than the .99 it would have cost to purchase, and you reach a far broader audience since the app would be free. Have you guys had any experience with in game ads? Do they work? Do they make money? What kind do you use? Any feedback would be great from anybody with experience in this field!
