A good question. To activate King George Square we could have chosen anything. Jugglers, markets, bands, who knows what else.
The answer is simply that my daughter, Amy, was inspired by her childhood experiences.
In earlier days we used to travel to my parents (her grandparents) place on a weekend for a family dinner. My parents always considered that TV was for "information", not "entertainment". So after dinner at their place, the TV would be turned off, and all six of us would gather for a board game.
In our case, the popular game was Chinese Checkers. It was perfect. Six players and fairly simple rules.
And thus the evening would progress with lots of laughter and conversation (a lost art) and fun.
Hence our passion for Giant board Games.
Ditch the TV. Stop playing online games. Get back to basics.
