ok so what i mean by "enviromental diversity" is essentially canyons, mountains, valleys, the whole nine yards but make them flow naturally through the landscape
and it would be cool if you could i dentify a planet/moon by its landmarks or enviromental hazards
speaking of enviromental hazards it would be cool if on planets like rask and rusk or charr there could be lava flows or volcanoes so you have to think about where you put colonies
or if they add weather tornadoes, storms, or even hurricanes for planets/gas giants
