Ho much end times have you played?

Si i was listening to the most recent Heelanhammer and they pointed out something. Most people are bemoaning the lack of any thing new for Fantasy over recent months. But really we have loads to be getting on with. 5 new books all containing new scenarios army lists etc.

So i wanted to ask how much have people played from the end times books?
Other than using the reign of Chaos and updated magic rules etc i have played very little. I am playing Grimgors Horde on Thurs so looking forward to that. But really i have barely scratched the surface of these great works. 

So thoughts? How many of the scenarios have others played and would a few dedicated people be interested in trying to play through the campaign at some point?

I have played a few games with Nagash both at GW and the club and have also used End Times rules in various games ad love it. I would be very interested in playing out the scenarios but would need to get a few more models to do them justice.
