The school my kids go to still has much of the same equipment it had when I went there in the 1980s. You know, the stuff just made from galvanized pipe, some of it hilariously awkward and unnecessarily tall. Even the newer swings are still plenty long.

Not every playground has been replaced with tic tac toe boards at ground level. That's just places that cheaped out. There are still plenty of playgrounds with equipment you can get seriously injured on. Though I don't know if I'd call that a metric to strive for, exactly.
