Very cool!
I also think Macrocosm mode would be a lot more enjoyable if land blocks were ⅛ the size (½ width) they are right now, so hills are more of a gradient. Still keep buildings the same size which would now be a 2x2 footprint. I find that the current size of blocks doesn't allow for much creativity and I get bored very easily. It would also open the door to smaller buildings for aesthetic purposes like bridges and sidewalks.
