There are two things that come to mind to answer this.
First, the map size for the largest map is supposed to be utterly massive. What was it, 10x the largest Civ IV map? In that case, it'll easily get to the point that if I have 5 cities and everyone else has 5 cities, then overall there will be only a few cities on the map, with lots of non-city stuff between.
Second, I think the map in general appears too random. Given that it's a random map generator...yeah, I'm not totally surprised. But really, wandering the landscapes and seeing a bunch of random stuff takes away from it all. I don't get the feeling I'm in a great post-cataclysmic world. I get the feeling that someone took a shaker and peppered the landscape.
All-in-all, cities just need...something more to them. I mean, really, here we are in a world, bringing life back where death used to be. Or death where life used to be. Whichever. I'd like for my cities to have opinions, comments, problems...in GalCiv, planets had their brief, special moments. It was easy to make a planet a 'focus' for one thing or another. I liked that. Late game, I usually had one or two planets that were production planets, with a number of others focusing on keeping citizens happy.
Ways to fix it...hm...
- I know that for the campaign map, at least, there are named landmarks. I'd really like to be able to name noteable landmarks in game. If the world is truly massive, we'll be able to distinguish between lakes, rivers, and mountains. It'd be useful, too, when planning out wars and combat.
- Cities need more...character. ATM, each city isn't special, it's just a bunch of similar buildings. One of the first things I plan to do for my faction will be make a slew of new buildings to throw into the mix. Either way, it'd be really nice if cities had some natural roads and whatnot. If I have a level 5 city, I'd love to see people randomly walking around. If I have a bunch of soldiers in a city, I'd love to see a group of them walking around on patrol. Cities do need more life put into them.
- Cities are all pretty much just carbon copies, it seems. I captured one of Relias' cities, and it was...surprisingly similar. Anything that could be done to make such cities seem less similar would be nifty. As to what, exactly, I don't know.

Another idea that just struck me...involves building cities at special locations. Perhaps in your explorations, you find the ancient ruins of Al-Ashteroth, Hallas, or Malaya. Building a city atop these ruins yields special, unique benefits. You get techs that are only available from having a city on these locations, as well as certain boosts to the city's stats.
What about Ithyrl, the resting place of the demon-lord Kroxir? In our travels on some random map, we come across the ancient dungeon. Our champions visit it, and we're presented with a choice: release the demon, or build a city with the sole purpose of keeping Kroxir bound. Suddenly, our faction goes from a normal one fighting with everyone else to the keepers of Kroxir, just with one city. And perhaps a target, should others wish Kroxir released.
And I'll be totally honest...I'd love to be able to see a massive city and think to myself, "wow, that's...that's big." Now, if I see a massive city, I glance back at mine and think to myself, "well, that's normal." A metropolis should be a great achievement, not the norm. And a metropolis...should be so much larger than other cities that just having one should make every enemy turn and just walk away in shame.
Things like that would add to the landscape, not to mention having the ability to build cities on special locations would give more connections to the land, and make special, rare cities that are actually something unique.
