Improvements were made to the naval aspect, such as reducing the cost for battleships and naval unit upkeep. Several new events were also added for Greece’s part in the war, along with capture events for Rome, Milan, Madrid, Sofia, and Washington.
The AI also received a boost for a better challenge, with German AI pushing harder in France and Central Powers AI building more subs, as well as improving the opening moves for Austria-Hungary AI. The AI for USA and Britain defend themselves much better if they are the only surviving nations. The settings for Easiest AI Difficulty have been corrected to give the AI a penalty, giving new and inexperienced players an easier war to fight.
