First playtest report:
Britain and France played max defense on Paris: they moved in the infantry from Morocco, the artillery from Algeria, the fighter and two infantry from London, and they moved the British fleet to the North Sea to stop Germany from using its transport to ferry additional troops to Paris on G1.
This Allied strategy was a little too effective. Germany attacked Paris with everything that could reach on G1, and the battle calculator showed that Germany had 75% odds to win (88% if Italy suicided its army into Paris on I1, but I decided not to do that), but Germany didn’t even come close – Paris was left with something like an artillery and 2 fighters after the attack.
Germany regrouped for a second attack on G2, again bringing everything that could reach, but after a close battle, Paris was still left with 1 fighter. I called the game after the second failed attack, because Germany had no navy, no air force, and even if it managed to take Paris on G3, that would leave nothing in the way of oncoming Russian forces, which would then be able to stack up safely in Poland and Romania.
The other areas of the board were playing out interestingly – Britain used its bid factories in South Africa and India, and ferried troops west from India to defend the Suez. Despite the added pressure, Italy managed to repel (for now) an American landing in French Morocco, and was dueling fiercely with British forces in east Africa. China made an unsuccessful attack on Kiangsu, and then lost Kwangtung, Yunnan, and Anhui to the J1 counter-attack, but China was able to hold its inland territories with help from Russian reinforcements, and China didn’t look dead at all. Meanwhile, Britain took New Guinea with the Australians, which was then blockaded by the American destroyer from the Philippines, so the Japanese couldn’t take New Guinea back unless they wanted to start the war with America early. This allowed America to stack its two Pacific fighters in New Guinea on A1, where they would be in range of either the Philippines or Singapore on A2. Of course, using the tiny Australian army as an expeditionary force meant that the Japanese picked up Sydney without a fight, but I still think the New Guinea stack sets up interesting options for the Allies. The Americans also had a carrier and a loaded transport near the Solomon Islands to play with.
I’m going to give Germany an extra artillery in Berlin and an extra tank in Poland, which boosts Germany’s odds of taking Paris on G1 to 95%, even without Italian support. I don’t mind the occasional upset in Paris if the Allies want to play maximum defense – I think the Germans would be able to recover from taking Paris on G2 – but it needs to be impossible for the Allies to hold Paris with 3+ units, because then Paris is back up to 9+ units by the time the Germans attack it again on G2, and if the Germans lose on G2 as well then the game is over before it really begins.
This will also put a little extra pressure on Russia; if the Allies evacuate France instead of reinforcing it, then the Germans might be able to pull off a G1 or G2 attack on Russia as a viable gambit.
