Mattman was saying (originally, at least) separate files for each sub faction, I suggested one document collecting all of the sub groups for each main faction into one. My thinking was that those who wanted the complete set could print out one separate book, while those who only really wanted the rules for their specific Amy could just print the 1-2 pages they needed and have those bound with the main faction book to make a single book.

My view is, that since these are going to be digital files we should be thinking about how to make them flexible enough to accommodate the various way different people might want to use them.

My understanding was that all the craftworlds would be grouped together in one document, while the generic or vanilla craftworld would remain in the other book, according to your proposal. If the idea, conversely, is to have each craftworld as a separate document, then I don't see that being a better option either, since it would just be too small to warrant being split in the first place.

Splitting Dark Eldar from the current book, and indeed splitting Harlequins and Exodites, I can understand, but breaking off the craftworld lists just seems like extra work for little gain to me.

As for creating additional lists being a bad idea, yes, it is just my opinion .
