Troupe Play and Sandbox Campaigns

[AmICoolYet?]

So if it's not saving me that much time, it needs to be better quality than what I'd prep myself--but that means it needs to better match my sense of taste than things that I write myself.

But the thing is, it does not only need to be better than what I'd randomly come up with, it needs to be a better prompt than the sum of all of the TV, video games, books, etc. that I am consuming at any one time. Doing something like that is probably so difficult that I have no idea what a "good" version would look like.
