Obviously as the originator of 3Forged you are the master at this - but J.Walton is right.  How you give people a sense of your though process and leave places to finish the game is brilliant.  Feels like a stand-alone game which invites every reader to finish it (not just the jammers) and that is super inspiring.

Now I want to make a bunch of part-baked games for other people to finish off in their oven.

This is really great, Paul. The premise is terrific, and I like how you clearly left some parts unfinished as an invitation to whoever picks it up.
