Yeah, most Sims can turn into vampires apart from kid, toddler and baby Sims.
When you begin in a Sim town (unless it is Bridgeport) there are no pre-made vampires. As the game goes on, than some pre-made Sims will become vampires. If your Sim knows a vampire, there will be a red band around the picture of that Sim.
If you mean what is the name of the Sims 2 game its called the Sims 2 Nightlife that's the one with the vampires.
Yes
Yes Vampire Sims can become pregnant in the sims 3. In fact vampirism is genetic in sims 3. eg: Sim+Vampire= Sim/Sim/Vampire/Vampire Sim+Sim=Sim Vampire+Vampire=Vampire
