OK, version 10 is now a available at BGG. An error was corrected and the Advanced Rail Network tech was enhanced a bit, hopefully it hasn’t become too terribly complicated - just a bit more useful.
We finished our second game with these rules. The Central Powers won it, Austia-Hungary was the star of the show, interestingly enough. It took Rome and jointly defeated Russia. Built a massive fleet in the Meditterranean and gained control of it where it was able to invade France from the southern coast while the Germans kept the French busy, and fleet battle after fleet battle kept the British occupied in the North Sea.
The Americans were sent to Italy to save them, which they did until the massive Austia fleet took the Med and entered Rome amphibiously. It was an 8 turn epic, at 1.5 hours per turn until the allies finally threw in the towel.
The tech kept things interesting. The more you accumulate the harder it becomes to remember to use it but that is a good problem to have. 😉
