I was a big fan of Warhammer back in the 80s when I was a kid (born 1970). I remember that it served much the same purpose as Total war currently does for me in that it had differing factions, politics, big battles etc but I'm a little worried at how magic is going to intergrate into the Total War system.
I mean, imagine all your carefully laid battle plans going up in smoke (green smoke probably) because out of the enemy lines, a wizard or some such performs a spell which drops your entire front line. Will magic be kept at the level of an average field artillery weapon do you think, or are they really going to ham it up?
