Innovative History & Extremes?

Innovative History gives you the Innovation Complex; bonus economy, bonus research and ships build on that planet get +1 in speed (if I recall correct).

History of Extremes, don't know.

I think the easiest way for you to solve this is to browse through then read the appropriate entry in the "Tech-Tree" XML-File. It may sound a bit daunting to a beginer but as long as you can navigate in WindowsExplorer [Not InternetExplorer] you should be okay.

Open WindowsExplorer. Click on 'Computer', then on 'Local Disk'. If you installed "GC2" in the default directory, click on that directory (or whichever directory you installed the games in). Click on 'Twilight', then on the sub-directory 'Data' and then the next sub-direcftory 'English'. Now in the right-hand pane you should see an alphebetical list of files. Towards the bottom you should see a file called 'TechTree.xml'. Right-click on this file, choose (Mouse-over) the option "open with" and click on Notepad. "TechTree.xml" will Automatically open in its own window [depending how you have customized your version of Windows of course].

Click on the 'full-screen' box [top r/h corner] and browse away. When you've finished close this screen and, if it asks, choose not to save changes (unless you do know what you're doing). And then you're Done and perhaps a bit wiser .

Heh, while I thank you for that information (which I may just use after this post!), it certainly shouldn't be that hard to figure this out.
