Hi James, I encourage you to review this advertising system which only advertise other games and is not annoying like Admob and others as presented to the user.
In addition checked by friends of the Forum, it gives much more gain than Apple iAds. In the case of iOS we can integrate it, but in the case of Android, where it generates a single file you could integrate it your. If it is as easy into iOS, I think that your very easy and fast way to add it to the exporter.
This is the link where we talk about the system in the iOS Forum:
Thank you and I hope you give it a look,
