A couple more I ran into that could add to this thread potentially.
Its kind of 50/50, sometimes i make valleys and sometimes i dont.Question for @Imperator Frank; when you designed Tellurus itself, did you already know where you wanted rivers and the like before you did the elevation map? Or did you decide where the rivers would go based on the elevation map? I ask because I want to redesign my own 'fantasy' Earth in a similar style.
Similar question regarding plate tectonics; did you do the mountains/elevated areas first, or the plates first?
This is great! Got the inspiration for it from Earth's "Snowball" period?
