I'm doing a little project with the technology tree at gamespot but I can't make out the following technologies:
Middle Ages:
1) The first three techs in the tree.
2) After Invention and before Chemistry
3) After Democracy
4) After Banking
Industrial Era:
1) Bottom first tech
2) Dead end tech after bottom first tech
3) Tech after Scientific Method
4) Tech after Steam Power (Not Industrialization)
5) Tech after tech after Scientific Method
6) Tech after tech after tech after Scientific Method
7) Tech after Flight
Modern Era:
1) Tech before Stealth (Looks like Synthetic ---)
2) Both techs after miniaturization
Or Firaxis could go out of its way to give us clearer tech tree shots...
