There have always been two approaches on how this series can be handled in 3D in my mind.
1) As a GoW combat heavy platform game
2) As a Demons Souls type game with platforming.
I think this game has the Castlevania look down IMO.The Castlevania series has never really been about the combat since it was pretty basic, but good combat in a game is always a plus and there does appear to be platforming in this game, something that Lament of Innocence lacked which made it NOT feel like a Castlevania game. The challenge of the series has been about patterns, timing and platforming. To me Castlevania games always need two things for me to be Castlevania.
1) Death
2) Dracula
The early CV games never only took place inside a castle the entire time. The games went from cemeteries, caves, underground caverns etc so saying the game does not take place in the castle the entire time "is not Castlevania" have probably not played the earlier games in the series. Its like saying Rondo is not a Castlevania game because there is a stage that takes place during the day.
