I asked infos about the seal where i bought it and they said Konami didn't make them sealed but they've been wrapped with some plastic by the Italian distribution company. And they're 100% official product(s) by Konami, that holographic sticker you can see it's an authenticy seal which must be putted and visible on original products as DVDs, CDs, VHS, other recordable supports and many other products also (laws in Italy regarding software piracy/plagiarism are quite harsh).
I also bought the mobile versions of Castlevania: Aria of Sorrow, Resident Evil and Devil May Cry

As side note, since i didn't try them (yet) i don't know which languages are available.
Well nothing huge but i wanted to share anyway ^^
