I am about to get a big blue cps2 system and its comming with Vampire Savior: World of Darkness , I can not find any info on this title, is this rare by chance?
Yes those are about the only two sites i can find info on it, and they are not very helpful. It seems like Vampire Savior: World of Darkness was the japan name and darkstalkers 3 was the us name. does this change the value at all?
Yeah. There are only two versions of "Vampire Savior" with one being a Japan only release. Neither titled "World of Darkness". Vampire Savior: Lord of Vampires and...well...Vampire Savior 2: Lord of Vampires (Simple! 2 is Japan only).
As a side, someone saying Darkstalkers 3 in the states tends to = Vampire Savior.
You're in luck, though, in that Vampire Savior (the first one) is considered the money game in the series by hardcore Darkstalkers fans (probably followed by Darkstalkers 2/Vampire Hunter/Night Warriors...omfg three names just for one game). Even if certain characters are broken as crap.
