I actually just experienced a CP win. Germany’s navy was key in this game. They attacked and eliminated the UK fleet on G1 and bought at least one sea unit almost every turn. They sent just enough forces west to contend with France and went after Russia hard with lots of art and fighters. By the time the UK rebuilt their navy and US could land troops in Europe, Moscow had fallen and Germany was building a battleship and transport each turn. This made the UK player turtle up and they couldn’t land troops to aid France after Germany took out there replacement navy.
Austria Hungary focused on Italy while sending a few troops to help in Russia. They took Rome on round 8 and turned their focus to France and picking off some of the northern Africa territories.
The Ottomans had a tough time with India and Egypt. It wasn’t until Germany sent their forces that took Moscow south to help them could they even maintain control of their original territories.
Other than the purchase of one fighter, Russia only bought inf and art. It just couldn’t compete with the German art rolling at 4’s. Moscow fell on round 5.
The UK went after the Ottomans and had them down to 11IPC’s at one point. They were able to rebuild a navy and land 6 units in Europe a turn but after Moscow fell, Germany could afford to put a stop to that.
The US probably could have done more but they were able to establish a transport bridge to land 4-6 units in southern Europe each turn. This was the main reason that Italy survived as long as it did. Once Rome fell Austria Hungary started to build a navy and force US out of the Med.
Not soon after Paris fell and that was that.
