not sure if this counts a "GAME", but it is fun, and useful for children and adults. It promotes AWARENESS. I'll purposefully not have my gi on, and have one of the senior students begin stretching and warm-ups. then i'll come in the room in about 5 minutes and tell them I'm going to be about another 5 minutes, i have to take a call and for them to keep keep working out. that first time i come in to tell them i'll be behind, i come in with lots of "props". a brightly colored shirt, clipboard, big socks, specific hat, etc".you can go as crazy as you want. then when i come in that 2nd time in my Gi, I'll ask each student to identify everything I had on. How many times has a victim of violence gave a description that was extremly generic? the point is for them to say..oh he had ona light blue hat, green shirt, a silver watch, wedding band, band-aid on his arm, clean shaven, etc.... i think you get the point. and if you really wear something outlandish, it proves the point and can be funny at the same time.
