The biggest thing these kids are missing is fresh air fun.
A good game of hide and seek would last a 1/2 hour a turn. Do kids even know what tag, buck buck, hand ball or red rover are any more?
You can't play a game of baseball during recess or lunchtime at school. Show up with a bat and it is confiscated and the child suspended.
We played pond hockey and schools had outdoor rinks. Even in the 80's I was taking my turn at flooding the rink at night with my neighbours out in Scarberia.
We also had bb guns, slingshots and firecrackers
