Bungie Sightings Likes It Sarcastic 'n Smarmy

Bungie Sightings has a new post up today on their observed progress of Wideload's upcoming Halo engine game, Stubbs the Zombie, as well as an offer of $5 to the person who can guess their answer to this question:

"Stubbs the Zombie is based on a previous Bungie engine. In the history of Bungie (and now Wideload) technical sequels, what sets this game apart from past attempts?"

The answer they are looking for is apparently sarcastic and smarmy.
