There's no reasonable way for the public to distinguish between whether they were hand-crafted or procedurally generated, though. While they can get a little same-y after a while, they do have recognizeable variation between them. Between those categories, Skyrim has a total of 202 such locations. 'The game has over 200 dungeons, all hand-crafted.' Not sure which game is being referenced here, but Skyrim is pictured: Skyrim doesn't use the term 'dungeon' as a proper name for anything, but the label could reasonably apply to caves, forts, ruins, mines, and dragon lairs.
'This is an enormous, dynamic world.' Well, isn't it? Dynamic (non-scripted) changes can and do happen on a regular basis, and the map is comparatively large by most standards. The 'It just works' statement aside (which was a silly thing to say from a software development standpoint, regardless of the quality or stability of the product), that's a pretty cavalier definition of 'lies.'
