I was pleasantly surprised with this supplement. It is very well done and anyone familiar with the Starmada system will of course have very little new to learn. A nice selection of ship stats are provided (mostly British and German but the other main actors are included as well). It compares well with Mongoose's Victory at Sea system and if you already play Starmada and are interested in WW1 naval warfare it is a must get. If you are a historical gamer un-familiar with the basic sci-fi Starmada system do not worry, the system translates very well to this period. The book is 88-pages and includes the rules for WW1 naval warfare, ship construction options, ship sheets, and six scenarios.
