One of the greatest problems with wargames is the perfect knowledge issue. I see the entire battlefield while you also see the entire battlefield. The fog of war is, for the most part, non-existent. Card Driven Games add a new element as you may not know what abilities your opponent has or whether or not he can activate a unit. PC games are able to act as a moderator, a referee of sorts, and give you that blind issue. But still, you are (usually) an omnipotent commander who relays orders.
