Technology Levels

Technology Level (TL) play a central role in the sci-fi war games I like to play, but I find it particularly challenging determine consistent rules for different levels of weaponry, gadgets and tactics. 

To aid me in working out a way to communicate the TL of a force I have tried to place various books, TV shows, movies and universes on some kind of scale. A few other people have done this and I consolidated various reviews and adjusted these base on my own views. It turns out to be much more challenging that I thought it would be because of the inconsistencies, contractions and perspectives. 

So for each universe I scored the lowest and highest tech used and identified other key technology milestones. I mainly aligned the scores with the TLs used in the Traveller system (see  Traveller Tech Levels).  

I then averaged various scores and arranged them in averaged TL order. I'm sure this could be debated for decades but it at least provides some guide for the gadgets and weapons that players may have access to based on the TL of the game environment they are in.
