Much more pictures are released by the Bundesarchiv. If not mistaken it includes the C for commercial use also

immersion/atmosphere
1. including historical data would add atmoshphere and immersion
2. based on Tutorial texts I suggest to reconsier layout of text when used for historical info
3. add historical photos (a lot have been posted in wikimedia commons for free use)

Army management
1. If I recall ...

Playing for more time, my additional impression:

- management of my "own" units (upgrade, buy, replenish...) becomes increasingly weird and difficult: it is still what drives me forward but it is really clumsy to manage. In PG it was even more clumsy, but it had atmosphere. Here it is clumsy ...

Overall: it lacks atmosphere - it tastes too mechanic

5 seconds: nice but clumsy
- no program icons (fav icon)
- first campaing choice: which campaign did I choose, what is it, how to go on?,..
- did I choose the unit or not
- ...

5 minutes: ok I get it
- interesting to play
- hard tot ell ...
