In all honesty, modern Vampire videogames are far too slash n dash for me. What the industry needs in my opinion, is some Hammer-esque with loads of suspense and a hero that isnt some kind of acrobat sword swiping weirdo with superhuman reflexes and magical powers.
How about the good old Van Helsing character, or even an average John Doe who has a smattering of knowledge and just everyday items and wit to hunt down and take on the titular bloodsucker. Think Horror of Dracula, Salems Lot, The Lost Boys, Fright Night. Above all, stick to the vampire we know and love, dont make them electricity throwing wizard genius types. Shoot plenty of 1st person scenes to draw players into the game (rather like Resident Evil) with creepy creaking floorboards and secret rooms.
Sometimes less is more, and the game itself should be foremost rather than what the characters can do. Jam out!
