Great mod. What a wonderful idea to take an already well-balanced game, and make it even better.
That said, I do think there is a bit of bloat here and there. Regarding fluids, I think there are too many. I like the idea of having another acid, a higher level one above Sulfuric that is used for more complex processes, but why have three? Hydrogen Chloride seems unnecessary. You could just use Nitric Acid to enrich Rare Metals, since you already need it to make Immersite Crystals. I am all for adding new things, but not of they have narrow use.
Biomethanol seems completely unneeded. Yes, you can burn it in the Gas Station, but why bother when you can just use Petroleum? Some of the other chemical recipes serve no purpose. Do we really need need a way to make water?
Water Separation also seems unneeded, since we can make both Hydrogen and Oxygen using the Condensers.
Don't take this the wrong way, the mod is incredible. The new buildings look absolutely amazing. I just dislike adding things that serve no purpose.
Cheers!
