I've got the Avalanche Press game stuff and its pretty nifty. It appears that they will be publishing a book of AH/WI/PODs so that one will have the background AH fleets and scenarios they publish.
Like so many people here, I've drafted a sketch of an AH AH (Austro-Hungarian Alternative History - or should it be KuK AH?) which the Austrians crushing the Italians at Caporetto, knocking them out of the war, and then taking up Wilson's first peace proposal and dropping out of the war. Undoubtedly, I had to really look at a POD before 1914 and started in 1900, IIRC. Keep Ferdinand Porsche in Austria and they just may have a decent automobile industry and - perhaps - tanks and armoured cars by 1917.
My take on WWII is that the AH join the Allies against the axis powers of Germany and Italy, with their fleet escaping down the Adriatic to be based ting your aproach to the suplements history(fused both the part of the First with the charactheristc of the Five to finally doing the six one,

) but again with your POD... Nazi Germany has no reason of exist(if A-H make than peace, besides looking as a betrayl, the Germans will do the same and still almost all of belgium and the North of France as Bargain Chips in the West, and waiting to the revolution in the east to snatch a lot for the russian) but make that for the sake of your timeline(but the butterflies are vital)
I'm Prefer my scenario, of a revenge war Between the Entente vs Central Powers
