Every game you play is 18+ because fetish content is still adults only. Just because it doesn't show any explicit sex or nudity doesn't mean that it's not innately sexual. The furry community as a whole needs to understand this. Do minors really need to watch you play these games?
This is coming from a guy who is down with pretty much any kink at all and also someone who understands and has lived that what you are doing whether you think so or not is making kids easier to groom.
Have a nice day.
