So pretty simple game, each of the kids in the Family Circus is given a Rosharan Shardic (or near shardic) analog (shown in the diagram below). Then a user posts a caption-less Family Circus cartoon, and the next person has to give the preceding cartoon a caption and then post another caption-less family circus cartoon.
Here is the diagram, showing the Family Circus analogs, and to start things out right, it is in need of a caption:
* Edited
Dramatis Personae update.
Dad: Adonalsium
Mom: Autonomy
I'll update the OP as new cosmere characters are assigned to recurring family circle characters.
