You are right though that Advanced Artillery, War Bonds, and Radar have probably the least effect on the game. (Those and Super Subs since there are few subs left on the board after the first couple turns unless you’re going after Japan heavily)
Whaaaa?? Radar is freaking awesome, even with Japan and USA!
I house rule war bonds - best of 2 dice.
Well, I suppose it depends upon how much SBRs are done and how much you move your AA around, because it does double your chances of taking out a plane. 🙂 In that case we can probably list War Bonds as the worst (arguably apparently) from Chart 1, followed closely by Advanced Artillery; and Super Subs as the worst from Chart 2 for lack of use, followed by Radar just by comparison to the other techs available on Chart 2 (LRA, HBs, Jets, Improved Shipyards), though I’m sure Germany would much rather have Radar than Improved Shipyards in most games given the chance. 😉 Anyway, none of this directly relates to artillery & Russia, so I’m done. I will stop posting my silly opinions of tech after this post. 😄
