So I'm getting through the DW rule book, and getting some great campaign ideas from this forum so far. The question that now comes to me, as I draw near the final pages of the core book is where do I go from here? I've browsed the FF catalog, and can see a few DW supplement books, and would like to know what is the best progression when looking at new books? Aside from pure adventure modules, which books bring the most useful new materiel? From what I've read in the catalog so far, I think that the Rites of Battle book comes with some of the best new stuff, namely an expanded set of vehicle rules. So what I'd like to know from you, my more learned colleagues, is what have you got out of the supplements, and what would be the best progression as I expand my DW library?
