Virtual Programming has released A Vamprye Story for Mac OS X
(http://www.vpltd.com/index.php?main_page=product_info&products_id=231).
It's an adventure game that costs US$29.95 and has a "7+" rating.

Here's how the game is described: "Deep within the walls of a gloomy
castle in the equally gloomy land of Draxsylvania, the young, gifted
opera singer Mona De Lafitte is held captive by her tormentor,
vampire Baron Shrowdy von Kiefer. Ever since she was transformed into
a vampire by Shrowdy and whisked off to Draxsylvania, her greatest
wish has been to return to Paris, continue her singing career, and
one day become a star at the Paris Opera.

"When Shrowdy fails to return from a nightly foray, she at last sees
an opportunity to flee. Together with her only friend and confidant,
a cheeky bat named Froderick, she escapes from her prison and tries
to find her way back to Paris. During her flight through
Draxsylvania, where she encounters some strange inhabitants and some
even stranger challenges, Mona must learn not only to accept her
vampire nature, but also to use the abilities she has acquired to her
advantage."

Players use a point-and-click interface to direct Mona and Froderick
through a detailed world consisting of more than 30 hand-painted
locations that utilizes a real time "multiplane" camera technology,
that entice the viewer to examine and explore. On her puzzle-filled
journey to Paris, Mona meets more than 20 3D-characters.
