1)germany
the true route to go with the germans is a sealion attack. if you play right and win in the north sea, and the sz off of scotland, you can probably take scotland G2. this presents an interesting predicament for england, who now is faced with attacking with the many infantry they have, or defending their capital. with the transports you bought G1, you can bring more inf over to england, and advance the ones from scotland on G3, while also bringing in all of your lutwaffe. if you buy fleet on G2, you should be able to clear the english channel. now you have two options with germany. 1)use the transports that are now in england to go over to canada, and try your hardest to take america, or 2)go all-out on russia, but be ready when america comes to retake some allied land.(if you go for america, your probly gonna need to turtle on your capital for when the russians come.) (also be sure to take france and do all the other normal stuff. and be sure to land 2 fighters in So italy, so taranto cant happen.)
2)Japan
Two words: america first. J1, attack at hawaii. with even luck you will probably be able to take it, and US1, they wont be able to take it back if you put enough of your fleet there. also, make sure to take the phillipines and hong kong.
now america will probly be focusing on using a KJF strategy, which is exactly what we want to happen. germany can go and take their capital and G5 or G6 if the russians havent slaughtered them to badly. but also, Japan needs to set up a shucking system in hawaii, so that they can reach america and help the germans out. this should take out the biggest foe(america) and allow you to reclaim territory on the mainland after all of the pacific is taken care of.
3)Italy
ignore egypt. it might seem foolish, but it will eventually fall. concentrate on getting things to Gib. and TAKING it on round 1. that way you can also shuck things to america every round starting on I3. also, be sure to clear ship out of the med. and try to take three of the 4 corners( so So.l france, greece, and Gib.) there. even with america in the game this early, they have a lot on their plate to deal with. the only help theyll be getting will come from the russians, and calcutta. those are the only 2 powers that will be left.
