This is a manual I drew up that lays out the various tech paths and trees in the game.
If you see any mistakes or typos or just have comments, questions and suggestions, please post them here and I will address them as much as I am able.
I just picked up this game about 3 to 4 weeks ago, so there is still much I am learning about it, but I have found having access to a manual like this helped me immensely with planning my future technology choices.
Happy gaming,
Bill Whitmore
