Don´t think the book with ~30 shiproster and some backgroud information is worth the price...
Full thrust offer more for free...
Of course counters for ALL the ships are free to download, starmade is on my opinion the better game (I like the hex).
But why I gave this product 5 Stars??
I would said: The Sovereign Stars
The Game - 4-5 pages in this book - works on his own or as campain for maybe every Star Battle Game (I tried it for a FANTASY campain. It also works very well!!!) It´s easy to learn, fun, fast, FANTASTIC!
(Sorry for my bad english, I´m from Germany)
[5 of 5 Stars!]
