Yea, this was my initial thought when I saw this thread. Its a shame as the iOS market is rather attractive, but the bge is good enough without this feature. If it was to be added, then yay, but I doubt it will happen any time soon.
But if you have already done your research and have found that there aren’t too many issues with licensing, performance etc… then hell yea, go for it. A fast route for blender to iOS store would make some serious ripples in the mobile development community.
Also, selling builds of blender to ‘try’ out features… I dunno man. This to me sounds like charging beta testers, which in my books is a no-go for something like this. But maybe I misunderstood what you were saying. If you charge for the finished product, then yea I think people would buy it. iOS store can be a very lucrative journey.
