Apple won't like this. Most of Apple's profit comes from in-app purchases of **** games where a level takes 1 minute and an ad shows for 30 seconds after and you can buy 1000 gems for $3 but for $5 you get 4500 gems (most popular!).What if they charged App Developers $100 USD per year for each app (to be in their App Store) ?
I heard that one floated multiple times when I was up in Silicon Valley earlier this month.
It has a side-benefit of forcing App Developers to prioritize their apps, which should theoretically greatly reduce the number of crap apps in the App Store !
The sate of AppStore games is terrible. Apple didn't allow Xbox Cloud too, so all you get is games above.
