I was recently given the JCoM core book as a gift; judging by the scarcity of recent posts here, I guess I’m a year or so late to the show.
My gift also included an Amazon gift card, so I can expand my collection a bit beyond the core rules. Looking at Amazon, though, I noticed the 3 Era sourcebooks don’t seem to be available there.
So my question is, what’s in them? How useful are they compared to the Narrator’s Kit, for example? Do they have much in the way of crunchy bits, or are they more expansions on the setting? Some of both?
Any input would be greatly appreciated.
