I meant rating for age restrictions by the App Store, not end-user ratings.
This is done on a game-by-game basis by a government agency in South Africa, and requires an additional fee, but, based on what I've read, other manufacturers have gotten their internal rating systems approved, so this fee is not applicable. Apple hasn't bothered. They just don't let South Africans buy games.
Do realize it's not Apple not letting South Africans to buy games. It's South African bureaucracy that's preventing South Africans from buying games. The barrier for entry is too high to justify the ROI for Apple to bother. Otherwise, there's no reason for a company to choose to forego more profit per effort.
