Let me start by saying I am intrigued by what I see, anything that reminds me of Kriegsspiel is guaranteed to get my attention.
I find it peculiar though, that all videos there are and most of the information shared seem to be about editor-features. Those are certainly great to have, and they seem well done from what I saw, but I would have guessed that Dev-Diaries about the editor is something for the last Entries. Instead, wouldn't it be great to have a more specific outlook on the game itself?
Is there, for example, a feature list around? I remember that there will be a courier system. But what about the FoW mechanic? Orders from superiors during scenarios like in SoW? Uncontrolled neighbors that can collapse and influence your operation? Sieges mechanics? War Bridges? Multiplayer? PBEM? (Just found the answer in an interview.)
Just throwing a few key words into the ring, that I find relevant.
Good luck with the further development,
A
