Another great product for a great game. Stars Without Number is quickly becoming my game system and setting of choice and this supplement, Skyward Steel, makes a great addition to my collection.
The book is extremely well written and contains a large amount of material for the price.
It can also provide inspiration for a variety of other SF games, such as Traveller, Thousand Suns, Star Wars, just about anything.
The sections on how to create a planetary space navy are very clear and the author provides three detailed examples.
I highly recommend this product.
