I don't know where you live, but I agree with you. Would be fun to create such an event worldwide as i think all the kids in the world would love it.
No one was playing with the board game at the time of my visit, but I'm sure there were some who checked it out. This festival lasted 3 days, so there was plenty of time.
I live in Nigeria and I also believe kids all over the world would enjoy those games. My favourite board games are chess, draughts (checkers) and monopoly. Ludo and scrabble are quite popular over here too but I am not adept at playing them.
