I should clarify, Germany and Japan do not need to BUY fighters, as they start with 6 already. I’m not saying they should feel free to leave them where enemy infantry can destroy them. :P
And yes, there are times I use KJF. No one is ever ready for it and almost no one can defend against it because they are neither ready for it nor experienced in dealing iwth it. Some have said it is very easy to defend against, and I’m sure when the game was new it was, since no one knew how to implement it either. But times have changed and it has become a very viable and logical strategy. In fact, I would actually recommend this as a route for first time players of Axis and Allies because of the simplicity of hitting Japan first and then hitting Germany. It is much more dynamic to hit Germany.
For instance: KJF: You take islands with England and America and then take the mainland with England. Russia stalls Germany.
KGF: You invade W. Europe OR you land in N. Europe to support Russia OR you walk through Africa OR you combine two of those avenues.
1 method vs 4 methods. Which is an easier concept for a beginner to understand?
Likewise, just for the shear desire to have a different game, KJF is fun! I mean, who wouldn’t have fun actually buying a battleship for once! Who wouldn’t have fun watching a combined value of 600 IPCs sink to the bottom of the board in a single engagement!
