Is it ever more efficient or should it be a last resort? I think it's something like 0.3 money for 0.8 rares, but how much IC is needed to make that money?
Sounds good, I'll install CORE now I have my new computerFor the record: there's a big difference in rares supply and demand between CORE and regular Vanilla. Within CORE even the USA has to import (or synthetically produce) rares, representing rubber and such. So rares are much more, well, 'rare', in CORE than they are in Vanilla. Plus, the construction and efficiency of synthetic plants is research driven for a player. To compensate, there are several event chains upping rare production, representing the historical building spree of synthetic rubber/fuel plants.
