Depends on the type of vampire, there are a lot of different versions, even if you count out twilight. Hardcore, old-style Dracula vampire: Must feed on human blood. Sunlight is death, silver burns, garlic burns, can't cross running water, holy water burns, ect.(no)
Then you've got "Vampire Huntress" vampires. Whole other society, with different power levels, 2nd gen and worse are a lot like Dracula vampires, except they can feed on animal blood if they want to, it's just not as tasty, and they're souls are doomed to hell. Master vampires are much more powerful, and they can still drink animal blood if they want.(Tempting)
Then you've got council level, where it gets real interesting. Sunlight will kill you, but it will take several seconds, holy water could kill you, but only if you were submerged in a swimming pool of it, Running water is tough, but you can cross probably a quarter mile or more, you don't like the taste of garlic, but it doesn't harm you. You can't enter a house uninvited, but you can compel most people inside to walk out, only those with strong minds who are also chanting prayers in the native language(Latin, Hebrew, ect.) can resist. Also, if they do resist, you can knock the house down with your various powers, and then enter the rubble. Also, you can still drink animal blood if you don't fancy killing humans. Every one of your senses is enhances dozens, if not hundreds of times, and you're also a telepath.(Very Tempting, other than the whole, damned soul thing. course that only matters if your killed)
Probably not, i like my soul not being damned.
Werewolves is another story. As long as it's not the original werewolf, count me in. Especially if it's the werewolf from either underworld or the Mercy Thompson series.
