While the campaign has concluded, the Kickstarter for Into The Majestic Fantasy Realms, the Northern Marches, is open for late pledges. This 200-page guidebook and maps expand the frontier of Blackmarsh out into the Northern Marches region of the Majestic Fantasy Realms.

Excellent!

Your reply will help thanks. 

So what if you have been working on this kind of thing for a decade and already published some of it but not all?  This is exactly what I have been doing with my Majestic Fantasy RPG. 

Would an extensive design note booklet (like a zine) be in order?  For example, I have a couple of dozen monsters but the "additions" that are common to all to make them work can be summed up in a paragraph.  One of them would be that monsters get an initiative bonus equal to 1/2 of their Hit Dice rounded down.
