Oh there's been plenty. Big campaign weekends at Warhammer World. A huge
battle across multiple tables at one of the Battle Bunkers, and putting boards out across the shopping centre floor with people bringing all their super heavies and flyers.
I have to say it's probably got to be at Games Workshop Manchester, WAY
back in the day, they made (and still make) some crazy gaming boards. We've
killed a couple of homemade Titans, one got brought down by a hunter killer missile from my mates Vindicator!
In this case it was a Skaven moon cannon, they wanted to blow up the
moon because they thought it was full of warpstone! The final game, after weeks of disrupting supply lines and trying to halt construction, lasted an entire weekend, and was full of treachery, double deals, quite a lot of Empire Steam Tanks and various Dragons.
I do believe the Skaven won in the end, but only partially! I think it was something like they managed to get it to fire but only blew a chunk off the moon.
