Although I can see the argument that for the experienced players the AA50 is more attractive and for everyvody there are too little changes to revised. I think actually Spring 1942 is actually quite different game to revised because of the change of the transport rules you cannot use many startegies developed for the revised.
Anyway I still cannot understand why the community would not give the Spring1942 more support.
The basic strategy is the same for the Axis: kill Russia as quickly as possible. The Allies might have a better shot if they decide to go after Japan, and both KGF and KJF strategies might have similar odds of succeeding, although this is highly debatable. From what I’ve seen so far Allied players are sticking to KGF (I haven’t played against a KJF yet and it is my standard Allied strat), which is harder to accomplish because of the German subs and airforce, plus any Japanese planes sent to Europe, and the transports’ lack of defense.
AA1942 is a bit like the ugly duckling. AA50 and AAP40 are new and bigger, plus there’s the stigma of being seen as the new rules being stuck on Revised along with a few map changes.
