Our Digital Viewing PDFs are digital versions of our books that are in full, rich colour. We would recommend these to GMs who use tablets or computers during their games. Printer-Optimised PDFs are digital versions of our books that have been adapted to have minimal colour to save ink in your home printer. We would recommend these to GMs who use binders and paper during their games, and wish to print out one or two sheets to use in each of their sessions.
