just a couple of responses, from information found in @Geoffers747’s Q&A thread:
What about interior rooms? Will we able to decorate or create interior rooms for the larger buildings we have?
Yes, absolutely, you’re gonna be able to furnish your rooms with furniture … those will have gameplay consequences, there will be decorative things like standards etc. that you can decorate the interior of your buildings with.
Can you customise the appearance of buildings as well? 2
Yes … eventually you’ll be able to choose the materials for the floor, the walls, you’ll be able to choose different patterns for the roof. And then you’ll be able to paint your walls through crafting, so lots of customisation.
For combat units, where you do exert more control, we will have the pathing options you would expect in an RTS: waypoints, patrol, etc.
