The storyline is great and the player identify easily with the hero drama. Today this is rare with all the Diablo close an such. The saga goes on since the medieval times. I remember that the hero was from the sixth generation, I think. In the modern times he was a truly formidable vampire. The plot really makes you want to save the girl, once pure, now lost to the paradise, from the evil who captured her.
The bad about the game is the AI from your followers, who sometimes attack the enemy for their own initiative, ruining almost all atempt to stealthing, and sometimes engaging in suicide combat. The enemy too seems to have a sixth sense and knows you are attacking him even before he can see you. But these are small defects in a otherwise great game.
