The KGF strat is not about ignoring Japan, no countries can be ignored, it’s just that allies cant do much against Japan for the first 2 rnds, and Japan can be partially ignored early in the game. The KGF strat involves slowing Japan down as much as possible, but most resources goes against Germany.
The reason why KGF is most popular among the best players is because a good axis player will make a too strong Germany if only Russia and UK tries to stop them.
And there is no such thing as KGF fanmania, it’s about the-most-effective-strat-fanmania
There is not really a KGF for many (99%) Revised games. A true KGF will include some US naval units to Pacific to distract Japan and force fight it … I only had seen a true KGF once in my PBEM games and it was in AA50. 99% of players do a Try Ignore Japan strat that includes sending all stuff to Europe and Africa, even the starting Pacific fleets. Most (99%) of players will counter this making a JTDTM, while some others will counter with a Polar Expres, that’s why I call the “so-called KGF” a “Try Ignore Japan (if you can)”
Allies can do a Ignore Japan strat only if Japan lets them. In my games I noticed that Polar Express is, at least, as good as JTDTM, and I’m pretty sure that Polar Express can improve because it has been used less (many play by memory with TIJ-KGF)
The funny thing is when in some games Japan gets diced J1 and anyway allied player lets Japan breath and TIJ just because they think that a Pacific Fleet is useless
My point is that in this or any future A&A games many players will never stop from trying ignore Japan, no wonder how bad idea is, how many income have Pacific Ocean and mainland Asia, how bad gets Japan diced, how good can be Polar Express or how boring can be ignoring Japan. KGF is a religion
