Flying Units
I read that that flying units do not exist. For example, a player could wall off his or her castle with volcano spells and units cannot fly over the volcanos. If this is true, it should be reconsidered for a fantasy game. I could not have imagined playing Master of Magic without flying units.
To further add to my confusion, I have seen screen shots with dragon units. Don't they fly and why can't they fly over volcanos conjured by volcano spells? Please explain. Thanks so much.
