I think klaymen_sk wasn't commenting on a lack of source material, but on the style of the setting. Koop doesn't seem to fit in there.
And RPG's of Warhammer are exact proof that Co-Op fits. (that's because they're technically co-op, if you haven't guessed yet)
Sure, but they are usually on a small scale (an elite squad, a small investigation group or so) and frankly, Warhammer is more about epic battles, so on a larger scale the coop won't work much.
Strange, because most RPG Warhammer scenarios I've seen are on a small, Co-Op LCG fitting scale.
Examples: Investigating Slaanesh cult in town (Peril in Pelargir, Stewards Fear, Trouble in Tharbad), trying to escape from the area that will get orbital striked soon (Escape from Dol Guldur, Flight from Moria, Flight to the Ford), and etc. etc. etc.
Warhammer is a universe, it's not "about", it's a container of content which can be utilized to create literature, games, movies and etc. There is nothing standing between them and real Warhammer Co-Op LCG.

But it's not the type of card game I'm talking about, It's a boardgame that happens to use cards as it's main components.
