Did anyone ever create a spreadsheet version for the weapons and defense trees?Actually I have the entire DL tech tree drawn up in Visio that I also have in .pdf format. It's a little unwieldly because it ended up being eight 8.5" x 11" pages, one page each for the Communications, Engines and Engineering Branches, two pages each for the Weapons and Defense Branches, plus a final page for the Planetary Invasion branch. However it does have a bit more detail in that it shows the attack/defense value and size of the ship component that the tech enables.
Anyway for what it's worth I've uploaded a zipped up copy to the ToE website, http://www.tyrannyofevil.com/viewtopic.php?p=6025#6025. It's not very large, only 32KB.
