Actually, one of the big headaches in creating your Own Traveller Universe is how closely do you stay to the established Traveller canon, and how much to you toss out. Then, for what you toss out, you have to create your own replacement material. Presently, I am about halfway between the two, using some Traveller canon material, mainly from the Little Black Books/Traveller-Starter Edition/The Traveller Book, and then creating a lot of my own material. That is were using the idea of the energy-absorbing "Black Globe Field" to get me to Piper/s direct conversion of nuclear energy to electrical energy, albeit in not so compact a form. No nuclear-electric flashlight batteries.
I have the FFE CD of the CT material, GURPS: Traveller, and some Mongoose books. Don't remember the exact details, but some of it is easy to follow and some not. I had the same trouble when I first got TSR's AD&D books. I learned that fairly well. Also have a web site for it if anyone is interested. Revamp, just have about 1000 maps, instead of the 2100 I had before.
