Firstly, the reproduction/ER increase costs. I will do a few calculations for different possible values for reaching, say, +20% in reproduction. You will have to choose then.
As for the Organic Facilities, I have to admit I am myself not fond of this trait, so I am not in a position to really speak about the other organic facilities. Nonetheless, you seem to make a point as Organic facilities are a bit improved if these facilities suit your playstyle.
I would support the reduction of the research requirements for the Replicant Centers, but not the actual improvement of the Replicant Center (contrary to what I wrote in my Last post), because I also thought of another factor. +20 million inhabitants a year is fine enough (for me at least) on well populated planets, but this would be a problem with planets much less populated. I find it quite strange when your tiny moon is "producing" 20 million settlers each year while it is only populated by 3 millions.
And as you cannot restrict the use of a given facility, then reducing the requirements would be easier.
Sure Oleg, if you are patient enough that is to "develop" the number of this population.
(Requiring micromanagement to put one million of these settlers to each planet with a Replicant Center, to increase the "creation" rates) Then it would be useful indeed. I have to admit I would prefer to use Atmosphere Converters, but that is merely a matter of taste. (Or that is because of my own silliness) Good point.
