So, I think the US2 has brought all the planets to a new level of amazing, but there's just one thing that the team can put effort in it.
The atomsphere!
Let's start with a well-known planet, Venus. Venus is a planet wrapped with a thick atomsphere, it trapped all the heat of the Sun and leads to a serious greenhouse effect. So that's why the atomspheric pressure of Venus is 90 times higher than the Earth. Just a little fact about Venus, nothing too special!
So another example is the Mars. Mars is completely different from the violent, hellish Venus. It's a place of cold and death. Today, Mars's atomsphere is mainly made of a thin, red layer of Carbon Dioxide.
Enough intro, so what I wanted is that the atomsphere thickness can be adjusted by adjusting the Surface Presure/Scale Height(Not sure how it's work, it's locked most of the time
). So now when you are trying to make Venus habitable, it's not a thick layer of atomsphere with weird white clouds above it in Alpha 15. In fact, the Alpha 14 one is much better because you can see the surface and the atomsphere at the same time. So when you 'cleaned' the atomsphere on Venus. You get excatly what it's looked like in Alpha 14. I will love that a lot!
Anyways, just a suggestion. Don't need to take it too seriously.
