What's not to like? First off, a crisp, clean cover that really pops and let's you know exactly what to expect from the book. Second of all, you get a really good variation of the rules formerly known as the 1st Edition Traveller Rules from Mongoose Games in the Cepheus Engine. Next, you get a clear and concise presentation of the Cepheus Engine rules along with a fairly extensive Table of Contents that lets you know exactly where everything is. Tying it all together is artwork that covers the spectrum of the setting. Everything from everyday life to combat is shown in the artwork to really give you a feel for what you can expect when you sit down to play and immerse yourself in the world of the Clement Sector. Yes as pointed out in another review, this is only the rules for Clement Sector and you need two other books the Setting book and the ships book, Anderson and Felix. This format however is not uncommon. For years Dungeons and Dragons has been a 3 core book set. Shadowrun has at least 5 books in their core set. Multiple book core sets are not uncommon and even needed for a really good game. Sure there are games that succeed as a single stand alone book but not many and not many that have longevity. Clement Sector is a rising star in sci-fi roleplaying and well deserving of your time and money. If you like Firefly, Dark Matter, Blake's Seven or the Killjoys, this is the rule set and setting for you. I reccommend you give it a try. I don't think you will be disappointed.
