Yes, that's right, the tech tree the game displays (and that you can find handily on the front page of this site) is incomplete... MAJORLY! So here is the completed tech tree. WARNING: I suck at art, so this isn't the prettiest thing. All I did was add lines to the existing graphic. RED lines depict a link present in the XML file that is technically not needed and could be removed, because the tech's prereqs already have this as a prereq, making it redundantly unneeded so you don't need it. ALSO, I couldn't figure out how to get it to display this in game, so if someone has that information, please post it. And now, the pic.
