I think this player movement is working poorly. So, I had a lot of "maybe went through the tutorial abandoned cities" and they disappeared and were replaced with coin. Nothing happened to two that have the main hall upgrading and no culture to polish.
All of these baby cities disappeared and were replaced by coin, for about a month. Now the coin cities have filled up with what appears to be baby cities, which we know tend to be abandoned easily based on how it seems that all of the baby cities that started with a previous "player movement" turned to coin, in the same kind of time frame that it took for new players to replace coin cities.
I don't get how this is thought to be helpful. Out of all of the "new" cities I think that indeed, 95%+ are cities that have just started. One is definitely a player movement, main hall level 11, trade, barrack, magic shop and all of the streets, residences and workshops are gone, so I got an abandoned city moved in. There were a couple that look to be around chapter 2 or so and I have no way of telling if they are still actually playing. And that's the big change from this round of player movement... So, maybe I have a couple of fairly low level players on my map after this latest player movement. I mostly have the same thing that was removed over the past month, so what was the point?
I am really seeing the idea that newbies start on a separate world is a very good idea, maybe with artificial players to take trades after a random amount of time that ranges from say a minute to an hour and once they reach a score of 500 or 1000 then move them into the main game. And I wonder if there is something undesirable programmed into my area that other players are not moved there. I have player movement turned off because there is a handful of good active neighbours, and it is away from my fellowship members. One of my fellowship members talks about having a super active map, but to move close to someone in my fs doesn't improve access to trading, and actually reduces it because shared neighbours and loss of the old map.
