I used to seriously underestimate Organized. At first I mistook the -50% civic upkeep for -50% city maintenance. When I figured out that wasn't the case, I was like, "Gee, then what's the point? Screw organized." I just didn't appreciate how big an effect half-off civic upkeep can have, especially during the middle ages when I'm usually running Vassalage and/or Organized Religion. Organized gets a nice assortment of building construction bonuses too. Courthouses are an obvious plus, but fast lighthouses can be useful for fledgling coastal cities. Not to mention the new factory bonus.
On a side note, I'm really bummed that Tokugawa lost his awesome Aggressive/Organized combo in Warlords. Organized was a really good compliment to Aggressive's warmongering. Japan's UB is kind of crummy too.
I agree strongly on the first paragraph, Civic upkeep is not trivial, even though I thought it was, and Augustus is just phenomenal for me since Granaries, Courthouses, Libraries, and Forges are the top priorities, typically in that order. Getting half of those really cheap is great, and as long as the city is pulling its own weight in upkeep and research/culture (hence the courthouses and lirbaries), then the forge can be built slowly while working cottages that are multiplied through the library.
Also, I lament the loss of Agg/Org as well. It was a great combo, but at least they provided us with Cha/Org, which is a decent replacement... still, I hope Agg/Org comes back.
