Yeah, those are good suggestions, Fryon.

Replicants seem fairly severe to me for human players to have, particularly when applied to systems with many colonies at level 3, and using alien breather types. They give the organic player a means to overcome three major gameplay issues at once:

* the need to use more than a few starliners
* the low build rates of most colonies due to low population
* the difficulty of amassing other-breathing colonists

Offhand, I don't think there's a way to limit the replicant centers to single-planet effects (is there?). So I'm thinking it might be more balanced if the effect was limited to 1M/turn/planet, and/or the research and construction difficulty increased a lot. It'd still be very powerful in the above ways, just about 1/4 as severe as present.
