For example, ever play a D&D campaign and one of the player characters tries to hook up with an NPC? It can be fun and entertaining watching the Bard court an NPC. You do a little role play, make a roll to seal the deal and, the DM says something like. "Rembrand and the bar wench take leave of the bar room and head upstairs for a night of romance." Who goes into detail about what happens in the bedroom? It's creepy, nobody does that. The only reason my son made the Choice in the game to sleep with the Drow goblin leader was because he was trying to avoid her trying to kill him at camp. He reloaded and choose to sleep with her and got graphic cut scenes. We play all kinds of "M" rated games. I don't let him play GTA because it's too human, too realistic. D&D offers a fantasy, slaying monsters takes the humanity out of it, like killing zombies.
