I saw a suggestion about the worn dirt on heavily used paths, however why not use stone to build roads? (Speed increase or less energy drain?)
From this, and since I had a starting locations a million miles away from stone. Could we have animals to domesticate? Such as for pulling carts (more resources at once), or for a different farming mechanic (as we need to get crops to plant in the farms)?
Also I may have missed it but can we rotate buildings?
