How so?
Because it's a good game.
What do you mean by kiddies? They are all at Fortnite xxd. So I think Minecraft is great because it is very varied and it is an open world game and you never really did everything. I also like the PvP system and the offered mini games
It's like Lego. But you have an endless building board where you can build almost everything and break it again. And along the way you develop your sense of direction and so on.
Even when I was 23, Minecraft was still very cool.
What exactly do you mean "kiddies"? Many grew up with it, including me.
