Beyond Earth: Extended Trade Route Duration

One of the more annoying features in Beyond Earth is that you have to "renew" your trade routes every 25 turns. What sounds reasonable in the first place, becomes very, very tedious when your number of cities and trade routes are growing in the mid- and endgame. To help with this situation you can modify the length of trade routes via the configuration that comes with Beyond Earth:

• Editing .xml file 
• Go to the installation folder of Beyond Earth, e.g. SteamApps\common\Sid Meier's Civilization Beyond Earth
• Open subfolder assets\Gameplay\XML
• Locate the GlobalDefines.xml with a text editor.
• Find the string TRADE_ROUTE_BASE_TURN_DURATION and replace the value by one that suits your needs, e.g.
•         <!--International Trade-->
          <Row Name="TRADE_ROUTE_BASE_TURN_DURATION">
              <Value>40</Value>
          </Row>
• Save the file and close the text editor.

Afterwards you can start the game, and you'll see any new trade routes will have that extended duration.
