Castlevania is no stranger to daytime areas.
Need I remind you all specifically of Simon's Quest? the whole game is based around a day and night system.
In SC4, wasnt the Waterfall area like sunset or something? Also, Bloodlines' Atlantis Shrine was Sunset.
It's not like LoS starts you off in a sunny area. Hell no, it starts you off in a pretty cliche besieged village, dark, rainy, and with Wargs everywhere.
It's afterwards that it gets sunny, but since CV is no stranger to sunny environments and old ruins, it never bothered me.
And It's no stranger to areas like the Necromancers abyss either. It reminded me particularly of The Abyss in Dawn of Sorrow.
Also, people complain about the name drops and continuity nods, but if they werent there, people would have bitched even more, instead about how they werent there. About how it's not castlevania because everything is completely original, including characters and backstory.
Instead what they did was adapt certain parts of the old mythos and incorporate it. Bernhards creating a demon castle, Cronqvists being Gabriel's true origins, Rinaldo creating the Combat Cross...
