And more importantly (to the kids), it’s got tons of fun content that other kids have made using those tools. This helps spread ideas and inspiration. They can see something cool and then “look inside it” to see how it was built.
Kids want to be doing what other kids today are doing. Hearing “I loved this as a kid” from a parent can doom something right from the start. Kids want their own experiences, especially as they get older. The technologies you have fond memories of were contemporary at the time you enjoyed them. Your kids also want contemporary experiences.
But most importantly, kids are unique, and often different from their parents. They might not like the same things we did as kids, even if we could exactly recreate them.
