All GTA SA's are rated M. The original release of GTA SA went from an M to AO, but this is not reflected on the package. When the controversy started heating up, Rockstar recalled all the copies, and GTA SA was not available for a few months, the original releases were selling for good money (especially sealed ones), but now that it's back on shelves and the controversy has died down, the price is back down. Some collectors may be willing to pay more for an original issue, others might not care.
