In LOS2, I found the lack of a chapel disturbing.
Agreed, although I can forgive it since the Modern sections covered that area. You had Victor's church, and the basilica.
Only areas Castlevania gave us were
- Ballrooms and a weird waterway
-Library and outdoor terrace
-catacombs/prison
-Gardens
-Toymaker's theater
-outdoor ruins location
then Alucard's game gives us
-haunted cursed wing
-Guest house
All nice and good, but a Clocktower at LEAST would have been nice. I guess City of the damned sort of fits that role, what with chains and gears and shit everywhere
EDIT:
Also, Artwork suggests that scrapped areas include a Castle sewer, a castle Laboratory, and a torture chamber
