Matt Finch just recently posted about an adventure design dilemma. He has a large number of areas that need consistent and thematic contents. There are, however, too many areas to make it practical to stock each individually. Thus, random tables for stocking. The choice is between many separate source tables versus one big table of results created from the results of said source tables (an X Y with Z complicated by A, with each variable drawn from a different table, or some similar composite).
I would suggest that the work involved in putting together the second sort of thing is a big part of what makes Vornheim easier to use than Seclusium. Despite the fact that Seclusium generates interesting results, they require a lot of post-processing. Which is time consuming. So it is worth realizing that what you are doing when you create tables like Seclusium is creating tables to create a table. That is (at least) two steps removed from something usable at the table compared to (potentially) only one step removed.
