Only 30 and 40 year olds with nostalgia are going to play it if it’s buy to play, why would kids pay for this game when they can play CS, Apex Legends, Fortnite, Valorant etc for free
Why do you want to play with children so bad?
What even is this question? Children are the biggest audience and the target audience for most of the games out there. Especially for multiplayer games.
Edit: I’m wrong
What even is your complaint? Who the fuck cares if kids don’t play it? You’re already wrong about them being the target audience; the target audience for 90% of games is adult men, 18-35yo.
Out of all the games you mentioned initially, only one is actually targeted toward a younger audience.
18-34 is the biggest demographic of gamers, making up ~35% of gamers. The various age groups older than that are ~40% of gamers.
