My youngest was being a bit rude trying to intrude himself into the game. So I told him to play on the other table and I will be glad to play a round after his brother and I were done. While getting blown out of the water, he was purloining dice out of my box and setting up a game of his own using Legos. When I finished I came over and found 16 assorted Lego figures and vehicles he built; lined up 8 on a side. In front of each side was four dice with the 1 side up.
The game consisted of rolling dice adding them up and moving a figure that many "steps". Then you fired on a guy. Each figure could move and fire once. He kept adding rules about shields and shooting weapons as the game wore on. I not sure who won but it was a lot of fun.
