Aspyr has named three titles it has brewing, including an expansion pack for The Sims.

The titles, currently under development by Westlake Interactive are The Sims: Livin’ Large Expansion Pack, Star Trek Voyager: Elite Force and Need for Speed: Porsche Unleashed.

The Sims: Livin’ Large Expansion Pack was released a few weeks ago for the PC. It offers new objects and architecture, custom skins, characters and situations. It also includes new careers, including Slacker, Musician, and Journalist. New buildings include a Castle. Visit Aspyr’s Expansion Pack pages for more information. The plug-in is available for pre-orders now, and costs $29.95.

Star Trek Voyager: Elite Force is the forthcoming release from Raven Software and Activision. It’s the first game based on the Star Trek Voyager universe, and pits players against a horde of Star Trek enemies – including the Borg. It offers single and multiplayer missions, and is based on the Quake III Arena game engine.

Need for Speed: Porsche Unleashed is a fast-paced, open-road game, offering the chance to drive an extensive collection of cars from the 50 year history of Porsche.

The Sims: Livin’ Large is available for pre-order now. Actual release dates and prices for all three titles have not been announced, Aspyr hope to release them in time for Christmas.
