Way back when in the year 2000, while the rest of us were fighting off Y2K, Doomworld hosted a contest. The goal was to create a Boom map using no more than ten sectors. The idea has more merit than one might think at first, as - to quote DoomWiki - "[a] sector does not have to be a single polygon. For instance, two squares can be separate and non-contiguous, but still be part of the same sector." What this meant for 10 Sectors was a ton of maps that had a bunch of "sectors" that only had ten different combinations of ceiling and floor flat, height, light, tag, and type. A whopping 146 entries were submitted, and the cream of the crop were selected and deposited into this, the 10 Sectors megaWAD.
