They are tiny, little hamlets. A couple of them could be villages, maybe. There isn't a single city. I noticed now I just wander around the world and dungeon dive, and almost never go into one of the "cities" because they bother me so much.
In each of the TES games, has there ever really been a "city"? Rome was a city, but the setting of Tamriel seems to predate the Roman empire. Should the next game have a city, it would mean it would take us at least an entire day
just to get through it. I can imagine the hate posts now: "Dang, Beth! Why'd you have to make the city so large, it takes a whole day to get through?? Arg!"
I love the small towns and villages of Skyrim. I don't have to spend time in them to get things done. I take great satisfaction galloping Shadowmere through these small towns as the people can only wonder where I'm going in such a hurry.
I wasn't a big fan of the city in Cyrodiil. I spent so much time just trying to get from one end to the other
for the simple mundane task of delivering a message. If the TES future does bring us a city, by the nine it had best not give us a handful of mundane quests to do just to "explore" it.
We'll have more than enough time to do that, if Skyrim's any indication.
