I don't agree that Castlevania "survived". It died for the most part with the creation of Lords of Shadow. In order to 'save' the series they had to gut it completely. That is not saving, that is just offering something in replacement with the same name attached.
I stand by the notion that Castlevania's issues are not with it's core concepts and characters, but in production values, choice of platform, total lack of marketing, and pandering to a different audience than what they should.
I also have an issue with Cox really saying he took a "risk" with Lords of Shadow. Making a series look, sound, and play, more generic than it's predecessors to pander to a wider audience is not a risk. It is minimizing your risk.
The biggest risk was alienating the old fans by the changes, mainly in story. Apparently they were scared of that, since they had to make up false impressions and basically lie to us in the trailers to get us old fans to buy it.
Can anyone name something in LoS that was actually original? I mean something Cox and gang themselves thought of?
I mean, he says they "made a change" when they pretty much copypasted things from younger game series.
You can change something by injecting ideas from other things into it.
In fact an overwhelming majority of highly regarded classic games had lifted their mechanics almost completely wholesale from something else. I honestly do not understand the 'hate' for games that use similar mechanics to others.
In fact that's how we got Symphony of the Night, the most popular game in the entire franchise. Guess that was a terrible game cause it took some exploration mechanics from Metroid?
