People are saying what I'm thinking AND saying. The world is bigger with less to do. Remember how many shell buildings there are right in the middle of Britechester? Endless 20x20 shells that are completely useless. Doubtless the pier will be rabbit holes - the Haunted House and even the Ferris wheel - if the Ferris Wheel is functional.
There's a football field, but it doesn't look like you can build on it... And the lake takes up about half of the world, forcing you to take huge round trips that eat up your day.
Some of the buildings in Strangerville just SCREAM 'a lot could go here' - multiple shells right along the road. In fact... Strangerville was the first pack with some kind of story.
The entire point of Sims 4 is that by moving between lots through a loading screen, the loading in general would be lessened. Having less lots doesn't actually impact this. I understand; you want to set some kind of theme for the world in the trailer, and put in a few basic families with personalities. But once those three basic families are in there, there's hardly any room for OUR families to interact with them! Also, the so-called 'basic' families always seem to take the largest, nicest lots.
Nobody wants to play as the basic families. Perhaps they like to interact with them. Realistically, you can fit one, maybe two of your own buildings in there, before you have to knock down amenities.
What happened to getting worlds the size of Windenburg?
