I've really enjoyed reading http://bitsquid.blogspot.com/ . It runs right from the birth of their game engine right up to the recent acquisition by Autodesk. They are heavy proponents of data-centric design with flat layouts (no pointer graphs jumping all over memory). The result is a game engine where almost anything (from rendering pipelines to physics models to ai) can be changed, compiled and live-updated on a nearby console in under a second.

EDIT: http://bitsquid.blogspot.com/2011/12/pragmatic-approach-to-p... is a particularly good overview
