Anderson's responsibilities on "Vampire: The Masquerade – Bloodlines" included game design, level design and creation, sound effects, and design and implementation of interface and artwork. He liked the game world compared to his last two games ("Fallout" and "Arcanum")and was happy that he able to make a game about vampires. However, he was not familiar with the table-top games, and had to do some research to understand the setting and translate it to a video-game experience. Anderson relied on player experiences from colleagues and online forums, to understand what drew players to the game. First, he learned that the main point liked was Vampire's focus on character interaction with stats, items, and powers taking a backseat. Main elements for the players’ experiences were constantly changing intricacies of the world and vampiric society. Second, Anderson had to reproduce the pen-and-paper experience to satisfy fans of the setting and give newcomers an accurate introduction. Generally, the character attributes from Vampire were easily implemented into the video-game format, while others (such as ‘knowledge of law') had to be left out. Also, dice rolls and randomness were removed as they would not have fit in a first-person setting. Disciplines were confusing and thus challenging to implement. Thus, a deviation from the board game was made to streamline the disciplines into the game. Furthermore, Anderson designed the ‘haunted mansion’ level of the game, which is famous for being "eerily atmospheric" and well-paced. Boyarsky recalls that "several people took turns trying to make that work, but it wasn’t until Jason took it over that it really began to shine".
