GURPS Space

Gurps Space is a great addition to the Gurps line of RPG game books. I personally own 60+ Gurps books so I can say with some authority that this book is a must have for any gamemaster that is looking to run a sci-fi game. This is a new edition of the gurps space book for the 4th edition of the game and is an improvement over the excellent 3rd edition of the book.
