Vampire: The Masquerade - Bloodlines

Vampire: The Masquerade - Bloodlines is an RPG game developed by Troika studios, set in White Wolf's World of Darkness universe. As a recently sired vampire, you must traverse the dark world of modern-day Los Angeles -- from raver nightclubs and secret underground caverns to seedy hotels and exclusive mansions on Hollywood's Sunset Strip. Embark on a variety of story-driven quests as you explore an open world filled with side missions, multiple pathways and characters to interact with. Yours is a living world, even though you cease to be.

VTMB had an extremely rocky development, partly due to Troika making the game on an unfinished build of Source. The game released basically unfinished and received one official patch after its release. Troika went bankrupt shortly after due to very poor sales. An unofficial patch by Wesp5 (and other fans of the game) has been worked on for many years, which fixes numerous bugs with the game and restores cut content.
