As I stated the same thing in "Castlevania confessions"
"CASTLE-vania" is already giving off its limits that the whole game takes place in one architecture and therefore turns off most gamers as they don't know anything about the franchise. They should change the title of the series. It will add more creativity to it. And some may disagree with this, but Castlevania's Dracula is just alternate retelling of the Bram Stoker's Dracula and is that character too according to bloodlines, but it had been an original character once, therefore you may ignore it's alter ego. This is what Mercurysteam has done. Gabriel is an Original Character and as "Dracula" of this trilogy, he's nothing like your archetypical Dracula. His apparel is completely different and goes nowhere near Vlad III Tepés or Dracula. It's completely original, but pays homage to the classic vampire media. Castlevania here has been original as well, therefore giving more creative freedom to the producers. It's the essence of a game that would make it a castlevania game. For example, some may think LoS doesn't reflect as a CV game, despite having the main character as a Belmont, have a whip, classic sub weapons, classic monsters, remagined locales, few known soundtracks and a castle. Yet, they will claim that BloodRayne Betrayal is more "Castlevania" than LoS regardless of having features that makes a Castlevania game. Why? That's because of the "Atmosphere" it gave and that's the keyword here. BloodRayne Betrayal projected the Gothic environment constantly. The moon being there constantly up in sky in most parts. The gameplay being 2D. The music being "Castlevania" although there was no classic tracks being played like they did in LoS, but the "style" was Castlevania. So these are the things developers need to know about the series when they are to work on them. But again, I played LoS and did question, why can't this be considered "Castlevania". Why can't ruins of an old city or mystical forests be considered Castlevania. Why is the moment when the series touches an unfimiliar idea is considered "different"? Why is the series "Limited" to these things. What make a Castlevania game "Castlevania". Why do some non-Castlevania games seem more Castlevania than LoS despite having none of those things that was Castlevania. Which is why, I feel that after LoS2, they should make serious renditions of their ideas and be strategic about what they want to do next. Castlevania is coming back and if this trilogy becomes successful enough, it won't be too far for the series to become mainstream. I mean for once, Castkevania was breathing the same air as mainstream games in VGAs. That's a huge step. But they will have to be careful from now on...
LoS is a completely new concept for Castlevania, it's pretty alien. A radical change. But, it's Castlevania in "essence" so therefore it's a Castlevania game. IGA's Castlevania was different and a radical change too once, and pretty successful too. But having the same monotone atmosphere and gameplay was making the series somewhat stale and therefore killing it slowly. There were times in OoE where I felt if was still playing Castlevania because that game relied more on the atmosphere than the essence that made it a Castlevania game. There were all kinds of weapon, magic and sub weapon glyphs except for a whip glyph... Like, seriously? And that's what Konami has to look out for, they're actually trying to make Castlevania big. If they are to do this, they'll have to innovate and get new ideas yet keep the essence of the series as well. That's what makes games successful.
