I mean most of us really love these games because they are challenging enough to give the player a driver to become better and better at playing, trying new strategies and improving game play and core unit composition.
What came to my mind as an alternative to the above is succession games. Something that is done a lot among civilization players.
The idea would be to get a few players in a group, probably something like 3-6 or so with a nice mixture of experienced players and newbies and then do a scenario or even an entire campaign.
The way succession games work is that every player playes a series of turns, then the next one takes over. Since Panzer corps usually has a lot less turns than civilization I guess one turn per player might be best.
I don't think PzC has any turn replay feature but we could simply record the turns with fraps for the next player and later cut the entire session together to an AAR video for people to watch on youtube

I think something like that could be enjoyable and since everybody gets to see how other people play it will also teach you something. Also the fact that everybody is only doing one turn keeps you very concentrated because you don't want to mess up that one turn

Let me know if anybody here is interested in such a thing.
