Just finished playing as Germans vs computer AI (+25% American forces). I liked this operation. Most of the battles were hard fought, and I love how it's tough to anticipate when reinforcements will arrive. I achieved a tactical Axis victory with a lot more bloodshed than I would have liked
I encountered a couple things that bothered me but they have mainly to do with the way CM handles operations:
1) I agree with some of the previous posts, the "no-mans land" should be set to at least 50 meters. With a 0m buffer zone, you deploy along the line and find enemy units nose-to-nose with your forces.
2) The end conditions for the Germans are a bit messed up. By the 6th battle, I had captured the entire map but the game still ran 3 more battles. The 7th battle the Americans got a few reinforcements that were crammed into a 1 inch strip on the map. I killed all those and in the 8th and 9th battles, I literally sat there with no one to fight. I moved all my troops to the very edge and sat there twidling my thumbs. I think this is probably a problem with how CM calculates victory but maybe the increased no-mans land area will help.
3) I don't know how CM computes the "advance" line but it is relatively easy to send a spearhead through the thin American lines and drive a force halfway across the map. Then when the starting positions are calculated for the next battle, you get a huge advance for the Germans. Maybe you could make the map narrower or add depth to the American defense to prevent this.
4) Just out of curiosity, what was the historical outcome of this operation?
That's about it. Overall, this was probably the best 3rd party operation I've played. Thanks for the hard work!
