I've got a feeling that this is the city view that was promised, and that we still will get a totally different experience when it comes time to do battle for the city. I mean, for god's sake, the wall there in the screen for Alexandria - when trying to scale in my mind - seems like it's about as tall as the palace, so that's got to be at least 50 feet or so (15 or so meters for all you non-Americans

). Thus when you say it "looks small," uh duh, of course it looks small, you're not down at the actual city level like you are in Carthage. When they began the zoom in you could see this sprawling city, and this is just a quick city view thing that you can do if you really find it valuable. If I had a unit of legionaries to march next to the city, I'm pretty sure you would see what I mean.
