My 40k Roleplay collection is limited to the Black Crusade releases. From those Black Crusade releases, all I really get for unit stats are a good selection of Daemons and Necrons…Now, I want to find out some rules for all the other unit types out there in the 40k universe. My understanding is that FFG has a spectrum of unit rules available throughout the 4 (and soon 5). But, where do I start? For example, where would I find something as simple as a Rhino? How about a Dreadnought? How about vehicle rules in general?
If I were to collect a small handful of books from the other systems, in order to access unit rules for things I can use in Black Crusade, what books would that list consist of? Basically, what is the essential collection of FFG 40k Roleplay books so that someone could have access to a wide variety of common unit types?
