Before your planning on cameos goes forward, I'd like to make the request that for this game, you forego them. Since this type of RPG is an experimental one, and there were a number of hoops jumped through to get it on board, I'd prefer that it not go off onto any sideroads with the use of cameos.
Sorry! But I'd really like this game to be tight and well written and something I can defend as a viable RPG type for the Barrow-Downs.
