Yesterday evening Aden announced that he had a game he wanted us all to play. He spent quite a bit of time setting everything up while Mommy cleaned the kitchen. There were little safari men, animals, a few cars, scraps of cardboard, and some Lego constructions all set out on the living room floor, and each person (including Noah) had an assigned place to sit.
The game became quite complicated, so these instructions may be hard to follow. But, if you follow them closely to the end, it really becomes quite simple.

We took our places and Aden began explaining the rules. First of all, this was just practice. So, most of the pieces would not be used. We would only need the little men. And dice. He found a square piece he had cut out of cardboard and instructed us that to use it (the dice), we would slide it across the tile floor to another player. He always told Mommy to slide it to anyone, but Mommy had noticed that there was a certain expected order - she would slide it to Wiley, who was always instructed to slide it to Aden.
Aden went first to show us how to play - he slid the dice to Mommy. Mommy then slid the dice to Wiley, and Wiley slid the dice back to Aden. At this point, everyone's man was to take "one step." We could move in any direction on the tile floor. But each person was assigned one square tile with all of his pieces. If your man took "too many one steps" and ended up in another player's square tile, your man was stuck. He had to wait until another player's man ended up in the same tile. Then your man could go out, and the other player was stuck.
We played for a while, passing the dice and taking one steps, until Aden got stuck in Wiley's box. Mommy would have landed there first, since she was a bit closer, but had also been told at one point that she could turn. Naturally, not wanting to be stuck, she turned just in time and walked along the edge of Wiley's box. But when Aden got stuck there, it became clear that Mommy was to rescue him. She was even offered that she could "go free" if she wanted, as a reward for rescuing Aden's man; or, if she wanted, she could stay stuck. While Aden was stuck, we learned that the animals were there to play with while you waited for everyone else to play and for someone to rescue you.

Once Aden was rescued, he decided we could play "for real," which meant we could use the other game pieces. First, everyone had to make their animals dance. Then we were told what each Lego structure was. There was a garage, a phone booth, two airplanes, and a house. But they were really all decorations. The real game was played over in the corner. Everyone followed Aden to the corner of the living room, where we were told to sit in a circle and play duck-duck-goose.
So, in the end, the real game is not so complicated after all.
