40 years ago it was the fear of satanism cult,Well, we might be less then a year away from this.
First games that have shady, illegal or criminal settings or player characters backed in will have to go: Wild West based RPGs, Spy RPGs, Cyberpunk RPGs, Mob RPGs, Superhero Rpgs and ones like Blades Against the Dark.
Games that in any way "glorify" money, so that is the bulk of all the future dystopia RPGs.
Any historical accurate game has to go, next: they are wrong or illegal on so many levels.
Then finally get rid of all violence from all RPGs. So that will leave, maybe, like the baking RPGs?
After all the typical, default RPG is about a group of violent unlawful unsanctioned murders doing whatever they want at will.....
in a near future simply fight, drink beer and eat meat at the inn will make DnD suspicious. That will be even more crazier!
