From the introduction: Welcome. The book you’re holding in your hands, or, more likely, you are reading on your favorite device, is the ultimate guide to 0one’s Blueprints. Just in case you didn’t know, we have more than 110 Blueprints on sale! That means you have about 700 maps to build adventures on. Blueprints are 0one Games best selling product and they have become the bread-and-butter of each game master. But why Blueprints are so successful? We could say because they are clear, meaningful maps, or because they are customizable to suit everyone’s gaming needs, or maybe because they are inexpensive and print out nicely without wasting your precious ink. I believe these all are weighting factors, but, to me, the main reason is because they spark our imagination. I could build dozens of different adventures upon a single Blueprint, and I am sure there are gamers out there who do it, everyday. So, here it comes this guide, to help you to find and use the map which best suits your needs.
