The original design is best. Such a cool logo for a very cool name. It always weirds me out when looking at the label on the top of the cartridge to the first game, with its lowercase C.
I remember Vic Rattlehead long ago posted an image of what was quite obviously the inspiration for the original CV logo. It looks almost exactly the same, same border and very similar font. He ripped the page out from a library book (lol) and scanned it, though I can't remember if it was the title of the book or the publisher. Wish I knew the name of it and had that image.
Also, no option for the Super Castlevania IV logo? Really? I suppose that would classify as the "Other" option, which is kind of strange 'cos I can't think of any more besides that one (unless you count Castlevania Chronicles, which has the same font but without the border).
The absolute COOLEST logo in the series, however, is the Super Famicom Akumajou Dracula one. I know it's not technically a "Castlevania" logo, but I thought it deserved mentioning. Made especially great by the dripping blood.
And I'll never understand why for the North American versions of the last two GBA games they raised the cross T in the logos. The Japanese versions look way better.
