Dependent Dropdowns: needed for Cepheus Engine Ship, Vehicle, Robot, Suit, Mech, etc…

Traveller and Cepheus Engine uses the Bill of Materials or Scope of Work method of building things. Its basically a Table where an Item’s attributes: Cost and Specifics, are arrayed and summed. 

 Here it is for anyone to use. My philosophy make it that someone who will make a better set of tools I WOULD BUY would come around, until then I will make these tools.  Someone hopefully will come around – make automated spreadsheets for making their Cepheus Engine stuff much easier,  and uses that automation and blender to make HARD SCIFI more accessible. Guys who are as bad in science as me getting to play “accessible” hard scifi until eventually we can wrap our heads around it. 

So to make 2-Parsec Playable I will be fixing Cepheus Engine ship Combat. I’m making good progress despite the Social Obligations of the Holiday. 

Sending good vibes this holiday. I don’t think nicco and I will finish in time. But Nicco made a bunch of Space Stations for 2-Parsec. I need to make a Delta V map generator for Mneme World Generator
