Split Belarus into 2 territories: Yes
Add German factory somewhere in eastern Germany: In Silesia
No teching for Italy: No idea
Additional balance around round 1 sea battles: Depends on the proposal
Increase neutral strength in Mexico: Mexico is fine right now.
Provide path to German neutral farming in South America (remove 1 infantry from Peru, add 1 factory for Bolivia, etc): Its not historical and there would be no way for entente to counter Germany in the area.
Have each major nation start with a different tech: Depends.
My proposals would be:
-Setting all options default low luck.
-Moving Mindanao and Luzon units to Manila
-Moving Hawaii units to Honolulu.
-Moving Cambodia and Annam units to Cochinchina
-Moving Malaya Cavalry to Singapore
- Making East Prussia 3 and West Prussia 3 (With Industry Tech, East Prussian fac would become more viable to press Russia if Belarus will be splitted)
-Making Bulgara German territory, -2 Income from Brandenburg +2 Income to Vienna for maintaining the same Production Powers, These units will be remain as Austrian.
(Goal is giving Germany more strategic options such as Helping Turkey against possible rushes in Anatolia. Building ships to protect Turkish fleet, Invading Russia, helping against Serbs etc.
-Adding newbie guide to notes (for to attract more player).
