Lots of really useful content here, this little book distills cool space opera tropes and presents them as tables full of ideas you can use in your game. Specific enough to be interesting, modular enough to be adaptable to most campaigns. I also like the way the tools are structured and linked together. Other campaign building products like Stars Without Number focus on describing the campaign world (planets, societies...), this one focuses more on things that directly affect the players (villains, threats, complications…). Highly recommended!
