@Imperious:
How does the “math” apply here considering this is technology? Technology introduces a new advantage so how does the math favor a 4-4 unit and not a 4-3 unit?
Math is game balance. I has always been the one of us talking about balance when you talk about history, this will be fun. The thing is that Tech is math as well, even if the dude that designed this game has not not realized it yet! On average one spend 30 IPCs to develop a tech and there is a rsik premium as well, since one can not choose the tech you want. So the reward one are looking for to put IPCs on R&D is actually higher than 30 IPCs, depending on how many of the techs that will be valuable for the player. This is the basics. If there are lousy techs the riskpremium gets higher. Lets say Russia only want four out of six techs since the other two are more or less wothless to him. The payback the Russian player would be looking for to develop tech would be 40 IPCs (30 IPCs plus 2/6 times 30 IPCs).
There are three factors that will count for techs and those are; attack, defens and special abilities like movement and hits etc. The easiest way to find out if a tech is balanced is to compare the cost of the new tech and see if will be costeffective in attack and defens capability. And then look at any special abilities that will be of any strategic value and try to put a price on that. This will be different from time to time dependant on the mix of your and your enemies force. But the bottom line is that a tech should be worth persuing and that is at least 30 IPCs of investing instead of purchasing normal units for the IPCs.
Talking about game breakers and tech, you self advocate a A-Bomb tech. One could argument that such a super tech would compensate for lousy techs on the breakthrough charts. Fair enough, but I think that the R&D is risky as it is and does not need to be more of a gambling, but rather more strategic. I think it would be better to have different charts for land, air and sea. This would reduce the riskpremium I talked about before. More over I think that any tech should not be a definitive game breaker. One should stay with the back bone of the game, and that is that it must always be cheaper to defend than to attack. No unit shall be better than an infantry in defens. Ok, must stop there.
