Ok I give up.
While I appreciate the helpful info given, it has no application to this.
At just over 6 GB Lucky Paradox MAY have squeaked by the permissions. However Hero's Harem Guild is 11 GB, and Harem Hotel is 10 GB. Both of them can be installed through the App, and haven't needed to use third-party sites like MEGA (who suck ass anyway). So either those two were grandfathered in because they were before the new limits took place, or the criteria for increases is actually way too easy.
Despite this, everyone is referring back to the limit of 4 GB - 5 GB MAX (with special dispensation).
The whole point of this post was WHY are developers so lazy that they choose to use third-party sites when their games are less than 2 GB, while others that are honking way big at or above 10 GB have no problems installing through the App?
