I didn’t think of those things and more meant the harsh atmosphere that we will need to have skills assigned to so our skin isn’t eaten off or we die because we can’t breathe. 
I’m completely on the same page and kind of why I did the post because I was fearing the same thing. I figured you all would have it covered but things like this came up in some conversations I had so I felt it was important to mention it. Variability and wide range of dynamics for planets will certainly be important so things don’t get old.
Thank you so much for taking the time to reply to this so people are aware of the plans.
