terraforming when do you stop?

[DAVIDARCNO (OP)]

When terraforming a planet, I realize when the colony cost reaches 0. 00, the planet is habitable without infrastructure.   Does anybody keep on terraforming to make conditions more Earth-like, or do you just stop and go to the next planet?

I try to make it "liveable" after reaching 0.000.  Roughly 10-30C if i can.

I try to make them more livable (Earth-like atmosphere). Getting it to 0.2 Oxygen, Greenhouse/Anti-greenhouse gas to bring temp to around 14* C, and the rest is Nitrogen, all without going to far away from 1 pressure.

In my game 0.0 basically is livable, as I've narrowed the habitability 'band' if you will somewhat.  So I'll just be moving on, when it gets to that point.

Dont forget - removal of every ounce of dangerous gas like ammonia, methane etc.

As I usually role-play my campaigns it really comes down to which nation is terraforming a planet, why they are doing so, what resources they have available and how many other tasks are waiting. However unless I role-play a really smegty nation or one which has too much to do with too few resources, I aim to make planets Earth-like. There is of course no real mechanical reason to do so.

For me it always depends on what I want to use the colony for, so for example in all my games I have a habit of making Mars the main research planet in my civilization. With this in mind when I terraform it I tend to only push the temperature up to around the minus 5 mark, this is just warm enough that folk could move about in the right clothing. but it also means those big science computers have a planetary cooling system built in. Other planets I might decide would be a perfect tourist type beach planet aka Star Trek Rigel and as such these will be left warmer than Earth.

There's one super niche reason.  A planet on the (cold) edge of habitability is more vulnerable to orbital bombardment dust wrecking its climate. Of course, that only matters if the planet suffers serious bombardment, so....
