I hosted my local group's annual Mordheim campaign this past weekend.
Put some pics up on the blog if anyone's interested in taking a look:
http://paintingtheleadpile.blogspot.com/We usually do this once a year, but in the past there hasn't been any real narrative to it - it was just "play a bunch of games, and see who has the deadliest warband by the end of the weekend."
This year we tried to add a strategic level by making it a map-based campaign in Lustria, where the warbands had to move around the map and plunder various locations.
It worked out OK but we'll probably go back to the simpler way next year!
