Havens served as the lead designer for the Private Party expansion pack for the 2005 video game Playboy: The Mansion published by Cyberlore.
[1] Under his leadership, the development team introduced additional features like organizing theme parties and new customization options for the player's Playboy mansion.
[1] While the base game's animations were gender-specific and lacked the ability to depict same-sex romantic interactions like partner dances between male characters, Havens pushed for the inclusion of content which would allow players to simulate gameplay interactions coded as LGBT in theme; he believed that it would be "philosophically" appropriate for the Playboy license and the company to allow players to experience living a "larger variety of fantasies".
[12][13] Havens is a featured artist in the 2012 charity compilation record Comp 175: A Benefit for Queer Programs and Services in the Pacific Northwest.
Havens was motivated to raise awareness about the importance of diversity in video games after attending the Game Developers Conference (GDC) event in San Francisco in March 2005, where he noticed that there was no discussion or mention of any LGBT themes or content throughout the event, and that there were no developers who had come forward to publicly discuss their experiences as non-heterosexual individuals or how it inform their work.
[18] During the 2000's, Havens was an interviewee for multiple media outlets about his experiences as an openly-gay public figure in the video game industry as well as his views on the presentation of LGBT content, such as The Advocate,[19][20] ABC News,[21] Gamasutra,[18][17] and Spike TV.
