I normally like the reinterpretation of existing maps, especially when several "classic" maps have been connected in an interesting new way. This map does have the element of clever connections, but alas all the "good" areas from q3dm7 have been deleted, and all the areas I only mildly - personally - care for from q3dm4 dominate the map. Alas, not quite as much fun as I had hoped for.
Reminds me that it would really be cool if id released the source for all of its maps.
