The Scrambled Continents map pack includes real geographic locations
with special scripts that produce randomized interiors each time a new game
begins. While the familiar outline of the continent’s geography stays constant,
the inner heart of the world changes each time you play for endless
replayability on countless plausible worlds. Maps include Africa, Eastern Asia,
North and South America, Western Europe, the Middle East, a thawed Antarctica,
new scripted maps for Small Continents and Oceania, plus one map including all
of Earth’s continents.
Well yes, the Earth map is already randomized, with the only constants being the shape and layout of the continents. This pack is a bunch of "zoomed in" real-world locations with more accuracy as to the form of the landmass. Granted, there's not much reason to buy map packs with all the free custom ones out there, but this really isn't much different from the other map DLCs they've put out previously.
This is a confusing add-on as most of this new functionality already exists in the World Builder as you can already regenerate the map during the first turn and you can select standard or balanced resources for each player on said map. Judging by those screen shots, it's not a particularly random regeneration, notice the mountain ranges.
You know what would be a better DLC? A replacement for those awful awful dark and humourless loading screens. Combine that with the nauseating soundtrack and there are two areas that need immediate improvement.
