Science Fiction Guidebook From the introduction: Do Porygon Dream of Mareep? is the official Pokémon Tabletop United guidebook for creating and running science fiction campaigns or introducing sci-fi elements into any sort of PTU campaign. Not every sci-fi campaign will benefit from using all of the content of this book, but GMs are recommended to pick and choose elements they like to create their own campaign world. Treat the book as a toolkit.
