yes, yes, yes, yes… and yes… 
Can you customise the appearance of buildings as well?
“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.”How complex can the buildings be?
“As complex at least as the one’s you’ve seen in the concept art …
ultimately we want you to be able to make anything … it’s just a
matter of how long it takes us to get there.”
