I'd like to play without eco-damage as well. No random planet life to deal with, I able to focus entirely on destroying the AI enemies.
In the alpha.text if you search for #WORLDBUILDER it'll show the options to change to alter the map at the beginning, you able to eliminate all fungus at the start, and eliminate global warming as well.
I see some settings under #SOCPLANET for your planet rating, that helping someone. I wonder if I changed the maximum from +3 planet, to +3000 if that'd eliminate all problems I had with native life. Or would I still have them, only be able to capture them 100% of the time?
I guess if I searched for "mineral" in the file, I'd perhaps find somewhere where it list how much damage the mineral tapping causes, and be able to change it.
Why does tapping energy also give you environmental damage, just as tapping minerals do? Honestly now, a solar cell isn't going to damage the environment. Does the unseen electromagnetic forces generated by the power lines agitated the planet somehow? Of course that's like asking why you get more energy when you build your solar array in the middle of a river.
