[Strider]

I get the impression that when playing against the AI that the oil fields are the primary way to achieve victory. It seems that the bombing and American public opinion are more secondary ways to achieve victory.

Now with multi-player, I've lost and won games using all four conditions. Normally, if the Allies can get their airbases for bombing established, they can win...but if the IJN keeps the bases beat down, then there is a better chance that public opinion will give the victory to Japan.

There was talk, a while back, of a patch that would include players being able to assign fighters to cap or attack. This might also provide a view of what planes are available...

As Fedor says, there are some edits you can make to make the current version of the game play a bit more the way you'd like.
