i dont know what your talkin about. i played as allies vs my friend who is very experienced and i won (wasnt easy tho)
u need to employ tactics man.
for example i made a raiding force, and built up like 6 bombers, and a strong navy, beat the japs out of phillipines and then built a factory there (dont worry if they did take it its not very useful to build there) and i kept strat bombing them (6 moves to japan and back to phillipines) and sending troops to sumatra, borneo, and the rest, until u have a decent invasion force, then its cake
jap player only got to 40 for one round in my game. be a coward in china, hold all your troops up in schechwan since rest of china is worthless and u cant attack to get korea or manchuria. build a good force of arty and infantry in india, hold back britains navy until its strong enough to severely damage the jap navy. use combat air patrols to protect your boats. watch for the strategically significant naval bases and airfields.
keep in mind tho no strategy is 100% in axis and allies. its like chess… on steroids… with luck involved!
