Contrary to Master of Magic Classic, which I enjoyed as a kid, but found hard to play nowadays, I considered Panzer General impossible as a kid.
Now, after completing a few Advance Wars games, I completed the first mission ahead of time.
It’s more of a puzzle than a strategy, though, since you can learn where all the enemy units are after a couple of attempts.
I didn’t know the game had a global campaign. Not only if you complete your objective ahead of the deadline you’ll receive more credits in the next mission, but all your untis from the first mission are transferred to the second one as well.
Interesting, if rather weird mechanic. Artillery is not very efficient against infantry, and not efficient at all against tanks (there’s a special anti-tank artillery for that). But it can counterattack unlimited number of times when any of the adjacent units are attacked. Making it very powerful when put behind a unit defending a city.
