As a parent, if you were to give 2 choices to your child right now :

1. Bagful of delightful sweets from Sweet Palace
2. Fifteen Minutes to play at this playground

I guess the obvious answer will be that he/she will choose to spend 15mins here.

Why?

1. Not only they got to play the slide or whatsoever facilities
2. There will be opportunities to know new friends too
3. And if they happen to play Digimons or PSP, all they need to do is just to establish a connection with the devices of other kids and there goes their game
