I wonder whatever happened to this game.
So what makes you say it’s completely over?
If you’re trying to go KGF, and Germany controls/contests Africa on the fifth turn, and you’re asking for advice, it’s probably an uphill battle. You would only be asking for advice if you were unsure that you could protect Moscow / crack Berlin, and with Germany fueled by African IPCs, and without a veteran’s perspective on how to run a tight logistic game with the Allies, I would guess probable loss for the Allies. All the Axis need to do is pump out a bunch of tanks and run a bit of interference with Germany’s airforce, which as you mentioned was quite strong.
It sounds like Japan is screwing around (no industrial complexes by turn five), which means you may have a chance, but again, I lack context.
If US was building some Pacific fleet, and Japan went infantry with very light naval/air support (pumping IPCs into 1 destroyer, then subs and/or fighters to match the US threat) then the Allies really are in trouble, because then probably Japan has some idea of what it’s doing.
If Japan was unopposed in the Pacific and built battleships and carriers, though, the Allies are probably going to win because Japan can’t just lay back and make Germany do all the work. Same if Japan used its transports to screw with Alaska/Hawaii/Australia/etc. instead of establishing a fast hard unit core in Asia/India to help support Germany’s push against Caucasus. You might see Japan doing both (i.e. hitting island targets plus hitting Asia/Africa) with five transports, but four transports on turn five with no industrial complexes built means SOMETHING weird is going on - like I said, either Japan was prepared to meet some unusual threat, or Japan was screwing around.
Yeah - what happened in the game?
I agree with Bunnies analysis - against a decent axis player, this game is probably over. But against novice players anything is possible, they may perform unfeasible or uncoordinated moves. In that case it is all about putting yourself in the position to exploit this. By this I mean armor for Russia, establish atlantic navy to threaten Germany, Western Europe and Eastern Europe.
