I've seen a bit of the comments about the French part of this campaign being too long and the Polish part too short. With my core being much larger than it used to be in PC1 or the PC2 default campaigns, it leads to more options in the deployment phase and more strategies to try, which also adds to the replayability value. There was no crazy Ebro scenario this time and I did not miss it, though 2 or 3 scenarios still had some very seriously sized enemy forces and counterattacks, which was enough for me.
Overall I enjoyed this DLC: the scenarios themselves are very decent, as in there are some interesting maps and the challenge was just about right for me. Please fix serious bugs before proceeding with new content. That's quite a list of scenarios to play through already. I'm waiting now for bug fixes before I start a definite playthrough of SCW and 1939 until these bugs are solved. It is especially important to fix these things because you can take you core force from DLC to DLC.
I do need to say that it is not good practice to go to new DLC while a previous one still has some serious bugs: a scenario that does not award any prestige points, support units not working with the allied faction's infantry. First of all: I was very happy with SCW and even wrote a long and positive Steam review for it (and I rarely bother with Steam reviews).
