The answer to that question can be found in my very first post above.
I did go back later, and read the more interesting ones - especially the design journals. I skipped the stuff an Alpha tests, Kickstarter campaigns and the store. The articles tell you some things about the game world, races, the character progression system, combat and other game mechanics. But all of those things - combat, character progression, races, story etc. - could equally be part of a themepark or a sandbox, and don't tell you much about what strategies the released game will employ to drive player retention, engagement and conversion rates.
The Foundation on the other hand is pretty much a textbook example of a specific such strategy.
