A Few Questions

[Old Soldier]

New to the game, read the guides, did some google-foo and still having trouble with a few things. Hoping the more experienced players can lend me a hand.

The game is great at providing lots of data, but not so good at usable information. The devs apparently don't quite suss the difference between the two.

What should be my FINAL targets for:
1- Overall atmospheric pressure. Is 1300 MBAR enough? Too much?
2- Temperature. Is 20 C enough or do I need 30? What is too hot or too cold?
3- Water level. Is 400 meters enough? Is 900 m too much?
4- Is there a way to remove excess Nitrogen? I can't find anything in the tech tree to do it.
5- Why does my Nitrogen level keep creeping up even though I stopped importing N long ago.
6- What is the minimum % of GHG needed? The max?

If anyone knows the dots and dashes of these things, I'd be grateful for the assistance.

Your goal is an Earth-like atmosphere of 1000 mbar. consisting of at least 700 mbar of N. 1300 mbar is more than enough.

20 C is OK; more makes plants grow faster and speeds up the CO2 -> O2 conversion. Too cold will make stages 4/5 of terraforming take forever. I don't believe that there is a "too hot" state.

400 m of water is the minimum required. Extra water doesn't really matter, although more of the flood plains will be underwater.

No, there is no direct way to remove Nitrogen. But having some extra N is harmless. I would assume you have Nuclear Nitrate Extractors running, but who knows?

GHG affect temperature. There is no min or max of GHGs needed to win.

Thank you! That is very helpful information.

I'd shoot for around 30 degrees centigrade, but that's up to you.

Meh, water levels matter. You can win with minimal water (400M), but if you really wanna turn Mars green, you need over 1000. 400-500 meters will get you around 30% green, @ 1170, I reached 77%. I'll keep adding till I reach at least 85%. I can deal with a few deserts, but the point of the game is to make a habitable planet that is at least as good as earth, not a dry desert wasteland for people to be exiled. But if you want Australia, you do you.

Thank you. Also very useful info. I appreciate you taking time to help me connect the dots on some the more esoteric nuances involved. I'd have never known any of that otherwise.

Thanks for the quiestions and the answers!
It was helpful.

I agree with OP about: "The game is great at providing lots of data, but not so good at usable information." 😅

Go for 1500-1600m sea level, or even more, but less than 1900. You need to have those rivers filled in the continental parts of mars for more vegetation.

The only reason for keeping it low would be access to resources, but you should have grabbed all you need in the earlier stages, if that was a problem.

the game needs a way to remove nitrogen.
