Expanding Atmosphere Types

[Randallw]

It would be good if temperature, gravity and radiation actually meant something or at least matched the planet. In one game I colonised a huge breathable planet and as we are RP'ing I wrote a story about it. Unfortunately although this supposed optimal world had radiation I could figure out, apparently less than earth, and gravity not too different from 1G it had a temperature of 300 degrees. Call that habitable, I don't. I gave up bothering to mention temperature. It's particularly annoying as it is a glaring difference from the picture.
