Thanks for the link. If I get this right the scenarios are focused on the west front?
Would love to buy a copy, but outside the US this is almost impossible to get.
Does this game still have an actively playing community?
Yes, it does. You have the Imaginative Stategist link that John provided above. In addition, if you are on Facebook, join the Panzer Blitz/Leader/A.I.W Group to see activity.
And yes, Panzer Leader is western front. Panzer Blitz came out first and is eastern front. Later came Arab-Israeli Wars, using the same basic system. I don't own AIW but many think it improved the basic system.
