We have a privacy rating system in place, that allows adult content to be invisible to site visitors and to members that are not of mature viewing age.  Whether or not you decide to allow adult content in your game, is your decision, however we do require any adult content, to be marked appropriately in the rating.  We require this on a file basis, so only the game moves or files with Adult ratings would be marked as such, the rest of the files will be available to all of NextGen RPG's community and visitors.
