Yes, I did world hopping. In 3.0 PHB we started in Greyhawk. Then we had to transition to Forgotten realms. We just hopped there with the help of a powerful Lich.
And also, one only need to worry about one small place, the one where the heroes are. One need not build the rest of the world unless the heroes go there.You can create your own settings. Some people would have you believe that worldbuilding some arcane art, requiring huge amounts of time and skill, but really it isn't. Especially when characters are just passing through, you don't need thousands of years of history or pantheons of gods.
One thing you can do is borrow a trick from science fiction. You think of one defining characteristic and blow it up to gonzo proportions. It might be kilometre tall trees, or floating islands, or planetary cities, or a lizard world. Political and social ideas taken to extremes also work.
As @Paul Farquhar says, you don't need to invest a lot of money or time into campaign settings to run a worldhopping campaign. The dirty secret of worldbuilding is that you only need to create as much as you're going to use for your games and the rest can be implied in the imaginations of the players.I'd like to do a multiverse spanning 'Rod of Seven Parts' campaign, but that would entail learning about (and paying for) far too many campaign worlds for my limited time.
Let's suppose you have not just a party that can jump from Eberron to Athas, but many.Just curious, why do you dislike it?
Why would there be many? Powerful magic is rare on Eberron, no reason anyone other than the PCs has ever made that journey.Let's suppose you have not just a party that can jump from Eberron to Athas, but many.
I mean, in this particular case my assumption is always that magic in Athas is defiling magic by default and preserving magic is difficult to learn even for native Athasians. So the Eberron armies you're talking about (or magical armies from any other world) are going to basically just make things worse, and possibly trap them all in Athas.Let's suppose you have not just a party that can jump from Eberron to Athas, but many.
Now why haven't they gone and cleaned it up?
It removes something from World building if you can have beings from a setting with a wildly different tone show up.
Because, let's suppose.Why would there be many? Powerful magic is rare on Eberron, no reason anyone other than the PCs has ever made that journey.
I prefer settings retain their own distinct nature without tourists.
I'm pretty sure that they would have better reasons for travelling to a difficult-to-reach plane than tourism. But if a world contains any level 20 adventurers they can do whatever the heck they want.Because, let's suppose.
Even if it's one party of level 15-20 adventurers that's still too jarring to me.
