I believe at least as far as the board assets are concerned in the AH version of the GS and FL there is parity, ie the same number and type of assets other than the dragon, the underground board and the furniture as tiles (which could potentially be used in new ways). I did an inventory of the game components that I think is accurate (though only the design components- not the cards so there will be differences there as well iirc). I didn't inventory my MB game as I'm pretty sure I have some extra tiles in there so I couldn't rely on it. The big difference there should just be the blank black on the double walls, and I think the stair tile unless they changed the count on the pairings for the single tiles. Getting a better count on the max number of walls or other features when combining with a single expansion was a major reason I inventoried them anyway.
