I am really wondering what

means!
The thirty years war is an excellent terrain for a wargame of AACW's scope. Factions aplenty, small armies, maneuvering, betrayal, lots of confusion and political events. It is a pity this conflict is not so much popular outside of Germany. Here we call it "der Dreissigjährige Krieg".
I have been looking forward to such a game for years. In fact I am not aware of a single game that has every ventured in this territory.
Conclusion: If the thirty years war is the "unannounced game with the BoA engine" I will pop a bottle of champaigne.
