if you're interested in vampires i highly recommend playing the
rpg game Vampire- The Masquerade: Bloodlines. It takes place in
modern santa monica, hollywood and chinatown in los angeles where
u, as a vampire of a chosen clan, have to fight for survival
against the other clans and the enemy sect, the Sabbat, who your
sect, the Camarilla, is enemy with. Its very non-linear, the game
is. You can roam around and explore, talk to people, visit the bar,
go into shops, get quests from NPCs, find clues at the beach, in
the bar, on the floor, almost anywhere. and you have to preserve
the masquerade, making sure no human or vampire hunter knows who u
truly are...and u have to feed on the blood of people u can find
without anyone finding out..to do so u have to look for drunk
people in the dark alleys, or find pay prostitutes then lead them
to a dark corner and feast on them... 
good game
