Introduction to the Mongoose era of Traveller. I would have LOVED this book back in the early 80's when I was learning to play Traveller. For a small intro price you can learn most everything you need to know about the Traveller RPG and whether it is right for you. This is a perfect example of a book doing exactly what it was supposed to do and no more or no less. If you are curious about Traveller then this is a good place to start. If you are already ready to go then skip this for Book 1; but I still think this si a good buy.
