This is one of the best RPGs, and even games in general, ever.
Highly recommend it for immersive worldbuilding, high replayability due to good implementation of role-playing PC choices, and atmosphere.
Doesn't require the player to be familiar with the "World of Darkness" setting at all.
Patches and mods might be required to bring it up to modern graphical standards, but even without that it is a masterpiece.
