there's no extensive evidence that it's not healthy, and by default everything is 'healthy', if the kid is happy, along with the various other metrics, then they are healthy

games can be a toy, but most video games are not toys, and almost all are designed to be competitive. toys are not competitive things

play is not about it being healthy or not, it's about if play is desirable or not

--

as 'kirion25' wonders in their comment, the problem is that almost nobody knows anything about play

for example one person mentions activities/functions that is leisure, and not everything within leisure is play (play is a subset of leisure)

nobody knows if there's any decline or incline in play, where's the extensive evidence that of play's claimed decline?
