Yeah I do remember that they were nearly instinct. That would make sense if that's so.
But since I am not looking for that, then depending what time-line we use they don't need to be a lot alive, but I don't want them nearly instinct either. Just enough :p.
I've seen the dvds, but the part with the vampires is not something I remember clearly.
I know they have weaknesses, but don't remember them all.
Well if we let Supernatural aside, can you tell me what kind of vampires you will do? It doesn't need to be 1000 or 2000 years old it was just to say not all mighty nor to young .
They're basically what you described in your opening post. They can go in the Sun, but it's unpleasant so they prefer the night, they can eat food, but it does not give them sustenance, they can't be staked in the heart, only decapitation works (don't care if that's included or not), Dead Man's Blood is poisonous to them, and they go in to a blood-lust when they haven't fed for a long period of time.
The Vampire I'd play wouldn't be insane, but he wouldn't be particularly good, either. He sees Supernaturals (Werewolves, Vampires, etc.) as inherently superior to Humans and has few qualms about hunting or using Humans he sees unworthy of life as slaves, but at the same time he doesn't go out of his way to harm them, either. He doesn't enjoy inflicting suffering on humans when there's no point to it (he has no issues torturing someone for information, though).
If you've watched TrueBlood, he'd be kind of like Eric mixed with Bill. Eric's callousness and Bill's control.
