However, I notice in SS #2 above, that there are both red and yellow rooftops in one asset - so that leads to the question - is roof color going to denote faction?
That's a zoomed-in view and seems to me that the roof tiles are all 'the same color,' just with varying saturation. (I see no yellow.)
I mention the zoomed-in part because I have a hard time imagining that you'd need roof colors to let you know what you faction you were viewing close up. Do you see the game somehow having a sister-city pair like Minneapolis-St. Paul with each half owned by a different faction? How else would buildings from different factions show up close enough together to get them confused at close zoom?
I don't mean the diferent shades of red on one roof, I am talking about the golden straw roof and the red tiled roof all being in one asset (SS#2) I, perhaps mistakenly, assumed that roof color would designate ownership. Not saying it necessarily should but that is pretty standard.
No I am not worried about two cities being close together and me being confused as to who owns which while zoomed in. I am just saying that it would be kind of weird to not have SOME designation of who's city you were looking at in the zoomed in mode.
