What is weird to me, how popular Minecraft rule34 is...
Minecraft was top 3 most searched video games on cornhub for 2023.

As for the topic, I have to say that most popular games are played by children (as well). Games like Minecraft and Fortnite.
I mean it's obvious, if a game appeal to all ages, there will be more people who will play it.
Parents will most likely let their children play "harmless" shooter than sexual suggestive games.
