Of course, there's many ways it could be executed so it's important to find a plan that keeps the essentials of the game (i.e. transmission chaining, or how information changes when sequentially told and interpreted) while keeping it fun to do.
In case there's enough mappers interested, I guess I can propose a plan just to kick off the brainstorming:
- I think we should keep our messages limited to an one-sentence idea, and each link in the chain is a pair of an interpreter and a mapper.
- The interpreter's job is to receive the last map, play it, and describe it as an one-sentence idea and tell their mapper this idea, and otherwise keep the idea secret.
- The mapper's job is to take the interpreter's idea and make a small map based on it, with a beginning and an end, and send it to the next interpreter in the chain, and otherwise keep the map secret.
- A secret "original idea" is given to the first mapper in the list, and consequently sent through each link in the chain.
Having the interpreter and mapper separated would also help keeping visuals and themes hidden, and hopefully produce some interesting results.
