Hello!
Apologies if this has already been suggested but i like the idea of being able to select a few colonists to travel on a ship to a new area. Once youve built your ship you can decide to go home ir start a new colony in a new area. You can load your ship with supplies to set up and pick your favorite colonist to move on.
Then when youve set up you can send word back to your colonists to journey to you. The chances of them reaching you depends on the distance youve traveled.
Thats about it. If this has already been suggested please delete :)
