Those who built the box would then put their box in a zone where it could fight with the works made by the rest of the teams. You would win the game if your box beat all the rest.
A game could be made where each team could build a box which would move and think on its own. The box would not be real, it would be a set of cards and notes.Some of the cards would tell of the things the box could do, like move fast, jump, fly, fight, sense and things like that.Some of the cards would tell the box when to do each thing.Those who built the box would then put their box in a zone where it could fight with the works made by the rest of the teams.You would win the game if your box beat all the rest.
Why is this Fun?
It is fun to build and then test things.
The goal could be one of peace. The box could be built to be the one to go through a maze first, or to make some set of goals come true. That might be more fun for some, but it would be less for some too.The goal could be to make a box which could do both, like a sport where one runs, then plays cards.There could be a real box, but it woud be more work, like most things though, it would be more fun too. (I think more work leads to more fun most of the time).The game could be played not by teams but by each one who comes, but it might take a long time. It could be a thing where there was a match each day (or each meal) and there could be bets on the box which would win. That would be more like the days of Old Rome than of the Old West though.
