Dear All,
I certainly understand the reasons for such alliances: for example, the Red Pact, once it accumulates some military strength, just has NOBODY to digest. Close targets (like Yugoslavia) are all in NATO alliance, and China is already too strong to target.
But from the opposite side, - Red Pact get unvoluntary involved in wars caused by some useless remote allies, - and then get crushed rather early in the game (mid-50s to early 60x).
By the way, please note that city improvements in this scenario have some missing parameters: like, TV station does not add anything, and all 'pollution control' buildings are one-sided: please check.
I have also noticed that at least till mid-game, no naval units can detect invisible (which is a bit strange, to my taste): I guess at least the destroyers should (which should give them some value).
