Pretty mucg designed for fantasy, but you could adapt it for sci fi with a little work. Not very detailed, more of an idea pull file for an overview of a settlement. Chasium Cites, and the World Builder's guidebook from 2e AD&D would help in the larger view and the street levels of this product.. which is how I intend to use them .. for D&D 5e.
Printed clean, just a few pages, easy to read.
