New Buffy game out in August! Buffy the Vampire Slayer: Chaos Bleeds. You can play as Buffy, Faith, Willow, Xander, Spike and Sid the Dummy(!), but no Giles.

The game's storyline seems topical, if you take Pure Evil as First Evil (if they are two different things, do they get along, or do they fight over who gets to destroy the world?): "Developed as a "lost episode" from season five of the television show, Chaos Bleeds involves an unraveling tale in which a dimensional bleed has been enabled by Pure Evil to consume humanity once and for all."
