Quote from the VtMR Official Site:
"Before your fall, you led a crusade against evil. Now you've become one of the undead creatures you once battled-a Vampire. Inhabiting the World of Darkness, you must face a series of brutal confrontations with your nemesis, Vukodlak, a powerful vampire lord. Your unholy showdown begins in medieval Europe and rages on into the modern day, as you track a soulless enemy in an eternal struggle to destroy him. For this is the only hope of vengeance for your tortured immortality."

Vampire the Masquerade - Redemption is a game whose story follows the adventures of a Crusader turned Brujah vampire, and his centuries-long quest for the woman he loves. The game features single player mode and multiplayer mode with storyteller, and there are many mods and add-ons available from various sites. While the game is dated now (it was released in 2000), it's still a decent introduction to White Wolf's World of Darkness. As an older game, it should be available for a low price - not a bad bargain for someone interested in a bit of dark roleplaying.
