I want the games to be under the GPL so that derivate work has to remain open source. But to have GPL apps in the App Store you need permission from all copyright owners. If someone forms Skeleton Key and releases their own version in the App Store, they need my permission since I'm one of the copyright owners.
So I just me giving my permission before anyone has to ask, but only for the purpose of App Store distribution. They're not allowed to re-license my code as proprietary for any other purpose.
Anyway, thanks for sharing.
I too would like to know your experiences as far as the business side is concerned.
