A simple synopsis - I went for "Russia 1st" - and Scott went for a big Russian push into East Prussia.
At one stage we had cut each other off - the Austrians & Germans had met at Warsaw, & the Russians had reached the Baltic west of Danzig!!
However the CP had better troops & I was able to maintain the pocket and he was no, so a massive part of the pre-war Russian army eventually surrendered - I think it took 3 or 4 moves for all of them to disappear - it was a big pocket!!
then the CP proceeded to take 6 or 7 Russian food hexes, and I think the Revolution came in 1915 and the Russians surrendered by 1916.
Italy entered on schedule, and with help was able to defeat the initial CP attacks - even pushing back into the Alps, but after a year or so they found themselves without as much support as they needed, the CP smashed through their lines, captured Genoa & Florence & thye were out by early 1917.
With the surrender of Russia the CP stationed forces around Romania & smashed it in a couple of turns for it's food and resources.
The British tried invading Gallipoli and did gain a foothold, but met with enough resistance to make it not worthwhile and pulled out.
On the Western Front the French and British had launched multiple human wave attacks throughout all this - casualties were horrendous and gains non-existant.
With no other fronts but the Americans about to arrive, France eventually invaded Luxembourg, rapidly followed by Germany invading Belgium - there was a fairly quick stalemate - despite both the UK and France being demoralised they had no shortage of troops (yet), and a few US Corps were appearing.
For the rest of the game the massive TE advantage in production slowly pushed the CP back - the TE invaded Holland, which held out for over a turn IIRC.
The French were completely out of manpower - their units were often only at 4 or 6 points. The Brits seemed to have plenty of manpower, but both countries were exhausted with most of their troops "E" class. However with ample production they had plenty of aircraft and artillery, and got assault troops before me - although I had also wasted points on tanks

So at the end Austria and the Ottomans still had "excellent" morale and plenty of manpower, as did Bulgaria. Germany was initially demoralised only at the end of 1918, but suffered another level during 1919 and only ran out of its manpower "stockpile" only on the very last strategic turn.
At sea it appears the unlimited U-boat campaign & occasional cruiser raiders achieved little except disrupting a few amphibious operations, as did well timed sorties by the Austrian and Turkish fleets in the Eastern Med. The Kriegsmarine did manage to seize control of the Nth Sea a few times too.
I don't know if any TE warships were sunk other than 1 DD Scott mentioned - the Turkish cruiser was the only CP naval casualty other than 3 or 4 u-boats.
So here's the butcher's bill:
