Game modifications:

     Note:  This  procedure  involves  editing  a  game file; create a
backup  copy  of  the file before proceeding. Use a text editor to the
xml files in the folders in the
"/strategy first/making history 2.0/modern europe/system/scenarios" 
directory. 

     For  example,  choose  the folder anmed "the limits of peace". In
this  folder  you  can  modify  the  country  (for example, the folder
"countryUnitedStates"). In this folder you can use your text editor to
change all the parameters of your cities in the xml file.

     You  can set the "IPU" of your cities to 200 or your factories to
200 production, etc. The highest level for transports or food are 4.
