Think of this more like a Classic Traveller "starter kit" than anything else.
I liked the document for the background that it provided, but always felt like there should have been more included to flesh it out and make it a stand alone product. As it is, it really isnt more than background information. That being said, it was never really intended to be anything other than that.
In my mind, i would skip this one entirely and go with the full fledged scenarios themselves.
