Well apparently you agree in a different way than i do, because I didnt mind LoS departing from "everything I knew about Castlevania" it was an interesting experiment in creative liberty with the franchise which I think was done pretty well.
I'm guessing, Flame, you are talking about the "idea" of "forget everything you know about Castlevania" and not LoS, because LoS most definitely did NOT forget everything about CV. If that was the case, we wouldn't have gotten all those names thrown in. I think Cox muttering that phrase was just to raise "reboot hype", but it defintely didn't not apply in full to LoS. There might have been some bits of LoS that didn't feel CV-ish, but there's a good chunk that did.
As far as the "idea" is concered, which is applied to most reboots, if you strive to do something that forgets the source material, you might have a better reception if you just make your own IP. That's the only true way to start a new project with a clean slate and no baggage at all. Maybe it's the times and the Recession, and that's the reason why everybody's playing it safe, hiding behind franchise names to push new ideas. This is a pretty big problem in the movie industry(well, American movie industry). Production companies aren't as adventurous as they used to be, but people forget that the only way to create new iconic franchises is to take a chance on a new IP. Look at Square Enix, who half-ass most of their IP attempts(with the exception of KH), and only focus on the big names. Had they shown the amount of dedication that the do to the FF series, they could've got some heads together and create 5 NEW RPG series with the same heart as the FF series. But it's safer to develope a new FF game, because it's a sure thing.
