I agree with Axis Roll. You should play a conservative Japan, the same thing you would do in KJF in Revised. Both sides are stronger, Japan has some interesting NAs up its sleeve and so does the US with nas/convoy raiding, but the basic remains the same.
He’s spot on with Germany being the bear. You have a huge incentive to keep a large German navy (convoy raiding the UK), and if you keep that up with large gains in Africa, you might be able to run over both UK/Russia.
For Japan, they have great ways to play conservative. Banzai infantry gives your land war much needed firepower/flexibility, you can use less fighters than normal and worry less about picket inf + aa guns. +1 dice point to a cheap unit is a very powerful bonus (yeah lasts one round, but that is often the most important round, and when you think about it most battles don’t last more than 1-2 rounds anyways). Kaitens gives you some much needed naval fodder, and in case those carriers aren’t reinforced, then it’s time to give the American’s a huge headache by suiciding into them. I would probably pick those two NAs. Banzai to break through the land war, Kaitens to give you cheap naval fodder.
I would also at some point consider going with lots of heavy bombers. That really keeps the US honest, because it is a very hard unit to counter navally speaking. Between cheap subs and heavy bombers, you could tie up the American’s navy for a while. Then hopefully Germany is going nuts, and if it isn’t doing well, then hopefully it’s more of a dice issue or a strategic mistake, and if it’s neither of those, then it’s just time to up the bid.
The hardest part I think in AARE is that the US can conduct convoy raids on Japan; this really encourages a big sub strategy using naval industry/reinforced carriers. But on the flip side, Germany can convoy raid UK. You have to adjust to AARE’s ruleset, because it’s designed not to be exactly like AAR. German navy + victory cities are the biggest things to keep in mind, because those are the things that give the Allies headaches they didn’t in Revised.
