I started playing some of my WWI scenario. Wow I was declared on by Russia first. Finally I beat them back to Warsaw. Austria has some nice defensive hills around Prague and Vienna. Their army looked imposing and it was a very bloody battle, but I was not in any real danger. They moved towards Lemberg then, but their offensive had run out of steam. All I did then was get valuable experience by killing their hurt units. Of course my army was hurt as well and I had no real prospect of taking Warsaw. Not that early in the game.
