Which period/subject are you particularly interested in?

How about the North African Campaign, 1940-43?

Good question!
A propos of the original AOS, I recall that the ship list, though extensive, left out a great many vessels of the period. It would be good to have a proper ship editor, which would enable players to fill the gaps from their own research when creating scenarios.

Anything with the Russians (Zorndorf, Kunersdorf, Bunzelwitz, Burkersdorf), also Rossbach, Minden, Liegnitz. A revised version of Torgau ("Prussia's Glory") without the bugs would also be good!
