Thanks for the input.... Now I have a few ideas to work on...
I once did a huge load of tech adds in order to lengthen the game and make it more interesting... I found some paper copies of those ideas for the tech areas, facilities, ships, components, and so on... It should be easy for me to get the way these files work back into my head and do it all over again. Challenges like this are fun to me!
No problem on any overlapping families and such, I'll figure something out which will also seem logical.
