My experiences follow yours. My nephews/nieces are obsessed with Fortnite and video games in general; they'll play it for hours until their mom or dad tells them to cut it out and go play outside, where they will proceed to pretend-play "king and princess" (there can't be dragons because "she will be too scared"), or "house" in an old barbecue box, or any number of invented games. Or they will make pretend cheese soup in toy pots and pans and go around "serving" it to everyone.
