And you can now change the color of the lights. Which you can re roll yourself too, you can put any number in the box to change the look of the lights up into the millions I guess. And as long as you have the option under Appearance turned on for City Lights and the other option If Habitable selected it will generate a random generation of city lights. I am unsure if having a magnetic field has any bearing on if it creates city lights, but having that sort of protection from star energy is also pretty much needed for life too. The way the sim is now it just creates city lights if the temperature conditions are ideal, and it has a suitable atmosphere and water. I don't see where you got that is it in the description of the game because I didn't see it on the store page?

In short, life simulation in Universe Sandbox will be seemingly simpler and less diverse than what Sim Earth can do, but way more realistic. Here's an older blog post about our surface grids (surface simulation feature): Multiple materials include methane, carbon dioxide, water, and oxygen that can all individually change states from solid/liquid/gas and move from the surface into the atmosphere and back again). Right now we're building on our surface grids simulation we released last year, improving, fixing, and working on adding support for atmospheres and surfaces with multiple materials as the building block for life simulation> While we have city lights that you can flip on/off, any sort of intelligent life or spreading cities is not currently part of the plans for life simulation. Great question about our plans for life simulation.ДЄt its most basic, life simulation in Universe Sandbox will represent single-celled or plant-like life that can spread across the surface and change the color of the surface from space.ДЄ step beyond that might be to represent 2 types of life, one that uses oxygen and outputs carbon dioxide (animals) and the other that does the reverse (plants).
