War Wagon was older than any of those, and came from a different era of gaming; it was about the size of a chunky chariot and had six guys in the back with a bunch of complicated rules (but, back then, using twelve different types of dice was the mark of a REAL MAN).
Dunno what they are going to do with it this time around.
Quite excited about this sort of stuff; I am not sure how many of the new releases can find a place in my army, but I am certain there will be useful bitz for conversions and a healthy injection of inspiration. Looking forward to this indeed.
