From all this opinions that i have read, i'll like to say that the series need to get refreshed with new game play elements, scenario, music, graphics and the design of characters or the number of equipment isn't a bad think for the series that needs to change.
Just remember the last old school Castlevania and when Symphony came out! I was left speechless when i saw the first screens from the game at a games magazine, that i went and made them posters for my room.
That was something new and awesome. So if IGA can do the same thing with this game or at least if he can't with this one with the new ones for the next gen consoles.
If he don't do that, then the series will die and it will be a same. Also Castlevania isn't like FF and that's because unlike castlevania that is dying having the same formula, it's FF is different from each other at game play, scenario and characters!
