You're funny. Castlevania is not Zelda in disguise (not freaking dicise). They're similar in the manner of gameplay. and such but they are not clones. While Lament and Curse aren't horribly originial or anything, it is no Zelda clone.
By the way, Yu-Gi-Oh! is awful, and yes, I read the manga (including the fan named "Season Zero" (or whatever) which the last episode of it was the first episode in the 4Kids dub). I didn't enjoy the series whatsoever. If the world has any decency, there will be less Yu-Gi-Oh! (do I add a period here?)
Magic: The Gathering ftw anyway. Better than the Yu-Gi-Oh! TCG.
I digress, there is no Zelda in your Castlevania and there will be no FF in your Castlevania or Yu-Gi-Oh! or whatever.
