Technically, there is no way to allow unlimited rounds/game turns. You can, however, make this number quite large, which is almost the same, no? You'll have to edit a text file, but other than that, it isn't too hard to do. Instruction:

1. Open Windows Explorer (not Internet Explorer, using the WINDOW Key + e keyboard combination)

2. Navigate to the proper folder, usually some place like:

C:\Users\XXXX\Documents\My Games\Sid Meier's Civilization 5\MODS\SMAN's World at War Scenario - The War in Europe (WW2) (v 2)\LUA\SME\Scenario Specific Files

Where 'XXXX' is the user account you installed the game under

3. Using Notepad (or some other text editor), open the file called '090_ScenarioGlobals.lua'

4. Find the 10th line in the file, which looks like:

g_iMaxTurns = 84

5. Change 84 to some other, much larger number.

6. Save the file, exit Notepad, then re-load the mod in Civ5


I'm not sure, but it's probably a good idea to keep the number a mulitple of 12. I don't think it will crash, but it may interfere with some of the scoring functions (but I doubt it). So, is you use this line:

g_iMaxTurns = 120

The scenario will run 10 years. Using 240 turns will run 20 years, etc.

Good luck!

Thanks! Keep on rocking
