I've watched the playground at my old elementary school get stripped of anything resembling "fun" and gradually replaced with safe, rounded edges.
It used to have a huge rope net (suitable for playing spiderman), a tire swing, bridges, wooden spars shooting diagonally off into space 15' off the ground to shimmy out and jump from, metal slides with little or no sidewall, monkey bars, knotted swinging rope (tarzan!), giant tractor tire sunk on its side in the ground, and the whole structure topped out at probably almost 20' tall.
Now the kids who "play" there can get all of 3' off the ground, surrounded by railings, and have a lovely plastic spinning tic-tac-toe game. Woooo. No wonder they prefer to stay inside and play DDR (hey, at least it's exercise). I would too.
