Academies are awesome. So much so that spamming them is a standard tactic. Assuming they should be nerfed, how so? I put up a bunch of options for shifting around the yield/cost for quick answers, and I covered as many combinations as I thought of but post more creative ideas if you have them. BTW, w/ tech refers to something like Protogenetics which gives +1 culture to academies. Do keep the array in mind which gives 1 science and 1 energy and can gain 1 more science later. So there is a +2 science +1 energy improvement as competition so going too low in yield to too high in cost for the academy can remove it from serious use all together.
