Inspiration is a funny creature. Sometimes it's a demon that tears at your brain 'till you write a thousand pages and sometimes it's a ghost who won't visit you no matter how much you beg.
This morning I was looking over my printed copy of RBH2 and kind of daydreaming about the session of Supercrew I recently GM'd. BAM! Inspiration. I wrote a fresh outline of what I need to do to make RBH3 happen and then immediately followed that with about five pages of actual mechanism changes.
With a constant flow of inspiration, I may be ready to present RBH3 in just a couple weeks. Keep your fingers crossed that the demon sticks around for a while.
