I really enjoy doing Game Workshops. Get a group of people together and invent some fun. I’ve done these at festivals and public events, and sometimes the results end up being pretty good.
Speedway 54 is one of those games designed by a group at a festival. A deck of playing cards, a pair of dice, and in the original we used colored stones and coins for our tokens. The brainstorming went really well, and the game was so much fun, I wrote it down.
