First of all, thank you for sharing your work.
And now some feedback:
Played at diff. IV, vanilla OoB version 9.2.4
scen 01: OK, a bit easy maybe, but OK
scen 02: what "Bobster66 " said. As this is supposed to be a campaign, some more land CPs would be nice. Expecting a defensive scen, I've retreated everything the first turn. And then waited and waited for something to happen. Even the enemy airforce seemed more or less idle after the initial attack on turn 1-2. The AI started the attack on my position finally on turn 10 or something. But they had nothing: weak conscripts against heavy tanks in the open...
Basically I played the first 10-12 turns with my airforce and long range arty only.
And then defeated them entirely using only my airforce and core land units, which was 6 infantry, one tank and one arty piece. (Okay, granted, it was not *only* my core units, but let's say they did 90% of the killing...)
Sugestions:
- add transpoprts to enemy infantry, at least engineers and the heavies.
- more enemy arty and WAY more "real" infantry (no conscripts) and tanks
- AT units to the enemy
- and: the enemy planes dropped from the sky after they run out of fuel, don't know why

For the consecutive scens to function properly, you have to include
all core factions in the following scens, i.e. Germans and French. (I did that myself with the editor)
03 Nothing to do here really, finished on turn 4 or 5.
The idea is okay, but you have to add more resistance or whatever to make it interesting.
04 As the enemy has no supply, this scen is no fun and too easy also. And I think the fortresses are idle, too.
As this is a campaign, I'd suggest some player CP/core units slots.
05 This one's quite good actually, but I'd recommend a turn limit of 30. You could also do with 25 turns, but then you will need the required 20 infantry units to be in the vicinity of Prague (there are 19 right now LOL).
The last 5-6 turns I had to roam the map to find me something to kill...
Also there seems to be an error with the prim. obj. "capture Prague" not activating.
PS: Oh, yeah, one more thing: if you change the date to 01.09.1945 inside the spec tab of the campaign editor, the spec tree won't look messed up anymore.
