Ultimately, that's part of the direction I was going with it. For some reason, Adult Only means no retailers will carry it. If Steam starts carrying it, then more AO rated games will be made.
That said, things like The Witcher 3, GTA 5... these are about as edgy and dark as games really need to be IMO. They're essentially adult maturity level titles anyways.
Ahh... the look on a parents face out buying GTA 5 for their kid, when you mention off hand that it has an active torture scene where you have to pick and use torture tools on a person... Ahh, the look of fury on the kids face because they already knew.... the rage is palpable.
