Depending on the theme, i problably wouldn't mind as long as it integrates with the rest of the game. For me integration is the key.
That's the big difference between JtB and Strangerville and the reason i bought the later but not the other...
Strangerville has a story going on in it's world, a story that you can choose to pursue or not. But you can still play a regular life in it's world, you can have a militar sim in other world because the career isn't related to the story, you can use some "story stuff" outside of the story, like the listening/blackmail machine, you have the paranoid trait that always reminds me of building a basement in my houses...
While in JtB it seems that we can't live in the world, stuff that works there doesn't work in the other worlds, even the inventory is different...
But i will always prefer open gameplay and i don't want to encourage them to do more story driven packs. They're always more limited than sandbox...
