I'm really hoping more people have tried this out this time than did the Lost Crusade. It's an excellent challenge; IMHO the goal oriented nature of it hearkens to the orginial MTW. If you haven't taken a run at it, you don't know what you're missing.

Fight a few of these battles and you'll see the kinds of armies the AI should be building to hold it's cities in the grand campaign.
