This is why vectorcube has been so entertaining. He reminds that philosophy departments still crank out people with a religious belief in this scholastic guff. Though vectorcube is a little fundamentalist even for an impressionable student.
Real philosophers like Nozick, Searle, and a few others I have time for, attempt to reason their way to strong conclusions using modal approaches. But there is common sense in the background usually guiding their efforts. With others like Lewis and David Chalmers, they build careers on taking logic to its illogical limits. And they certainly attract a certain kind of follower.
But the interesting question you raise is "what is a world"? Do you have a definition from your own readings?
I would take the systems approach and argue that a world is a system. It is not just a collection of objects (concrete, abstract, possible, necessary, or otherwise). It has to be always both its events and its contexts, its local and its global. So it is not even about "the largest scale". It is about how large and small are the system, the process~structure, about the relations from which everything forms.
The modal logic approach of talking about worlds as an atomistic collection - a collection of isolate objects - is clearly wrong on this view. If there were multiple worlds in any correct sense, it would have to then constitute the local elements in a global "world system". We would have to take the further step of spelling out how these separate worlds relate.
This becomes very clear in a process view. If worlds do not simply exist but must arise by some kind of development, some kind of shaping selection mechanism, then that process would have to be common across all worlds at some level.
Always if there is a figure, so must there be a ground. Even atoms require a void to express their relational properties such as shape, size, position. So if we do want to treat worlds as atomistic objects, we then just shift the discussion of the world context, the "void" which allows these multiple worlds to be distinguished, to a meta level.
