that sounds like 2nd or 3rd edition rules (i.e. “original” axis and allies), not 1st edition. are you sure? i’m taking about the very 1st edition… an edition basically no one plays anymore.
The 1st ed was w/ unlimited IC’s. Even ones you purchased.
Very unbalanced b/c GBR would get an IC for Persia, and move all of the India units to Sinkiang to allow US to buy the IC on the first round. Round 2 and beyond sees $ 60+/turn worth of allied armor pouring onto the Eurasia landmass to take everything over.
