This mod has been a lot of fun for me, and has definitely made managing my colonies a more involved and interesting process.
I do have a couple of things I would like to note.
First: Balance probably is a slight issue, and I might have to delve into the settings myself if that's possible to fix what I can (though it seems only some options are easily configurable). The Atmosphere Processor seems a bit pointless, given how little it contributes for example. The terraforming platform also seems quite pointless, because it gives less terraforming points than the reflector despite having a fairly hefty resource requirement - since it needs a lot of ship hulls and fuel to function. The Skyhook Anchor boost to accessibility is very small considering the cost, especially when considering things like Starport upgrades. The Kletka simulator also probably shouldn't produce cores so often, but I guess I'm just nitpicking now.
I know the mod isn't meant mainly to be balanced, but rather to expand options. Still, I think balance is a fine thing to strive for where possible. If it would be possible to implement more of the relevant costs or details into the config file, I would appreciate that too.
I just wish certain options actually were worth using. I would like it if the Atmosphere Processor for example was necessary for or would allow you to manipulate certain atmosphere conditions (like it being toxic), rather than all of them contributing terraforming points equally. Or if the solar reflector was only able to be built on colder worlds. Without that kind of distinction it's best to just pick the most efficient option for the case.
Second: In relation to the first point, the Atmosphere Processor and some other structures mention how they are affected by AI cores or Domain Artifacts, but the descriptions don't always say precisely how they are affected. I would recommend doing a pass on the dialogue if possible to make it a bit clearer to others who are new to the mod. Actually, having more precise time-lines or even just estimates of how long it takes for things would be useful - such as for the Military Police Headquarters.
I guess that's about it. I have greatly enjoyed the mod, and the idea behind it is great.
Especially in combination with other mods like Nexelerin it has helped the large scale features of the game come to life.
