Yes, I have observed my two nephews over quite some time now. Even play it with them sometimes even though I suck. I don't have any strong opinion on the matter, but it is strange watching a whole community of 8-9 year olds(!) begging for ingame purchases and discussing detailed specs of Assault Rifles with their friends. And it is pretty clear (to me) what drives the money in this game, and for example Rocket League. Parents paying for ingame goodies of children. (Yes I know 8 yo is young. But most parents will stop caring because of the peer pressure, every classmate they have get to play the game.
