To be completely fair, Panzer Campaigns has a zoomed-out view, even a jump map that shows big chunks of terrain and troops at once. But the structure of armies and corps is difficult to grasp in those. The zoomed out view in Panzer Campaigns even obscures some roads in certain types of terrain.
Tunisia '43 I'm ill-prepared and un-read. Books are on order and my interest on this campaign is now very high. On the meantime, I'm reading whatever I can find and consulting The West Point Atlas of War for a quick reference on operational movement during the battle.
Another thing that is helping me a lot to understand the "big picture" is other game from John Tiller, War on the Southern Front. This game is at the pure operational level, and the units are regiments/brigades (compared to companies and battalions in Panzer Campaigns) and above. Also each terrain hex corresponds to 10 km (compared to 1 km in Panzer Campaigns).
