In fact, I've found that for my games, what I need is usually just a couple of d6 tables to generate the whole "world" around the main campaign. There just isn't time for me to do more, or for my players to encounter more. Sometimes I'll roll for a full row, sometimes mix and match columns. The result is a table more or less like this pre-fabricated for each session. An additional table for treasure and rumors usually rounds things out nicely.
