Depends on the content, Like Seasons, I believe their main focus, as it was, is the Seasons and Weather, even before objects seasons and animations should be the priority.
If it was a Game Pack about a life state, I say, Focus on the Life State, above all else. their powers the animations and effects, then the objects of which they can interact with, then if there is still room, the world. Forgotten Hollow wasn't crucial to Vampires.
Cats & Dogs, Brindleton Bay could have been better, but I can see the focus was more on Cats & Dogs, not the world.
a pack like a Farming GP or EP, that ought to come with a New World.
University is a yes, that pack needs a campus to build on.
But if they wanted to Make expansions or game packs that focused on a place, France, Italy, Greece, England, Ireland, Egypt, just throwing those places I would love to go to, out there. I would love it. Maybe some as destinations, and some as full worlds.
And a French or Italian themed world could be perfect for a Farming GP I think.
Ireland/England could be cool with Sorcerers.
Italy, Greece, could have University.
