The big problem is that we have never had a proper Eastern front setup, only a bodged up default map.
So I thought I'd see what could be done to create an Eastern Front setup without having to spend huge quantities of time retiling an entirely new map. Taking the bodging a bit further.
So I took the tile map created by Prune/VonOben which uses Max188's Russia Summer terrain to create a default map without seas or oceans, and using bitmaps, created this new map:

I've retiled the costs and seas, used DOM's and Jel's utilities to flatten the water. I'm currently putting in towns and bases.
The thing is, although the tiled terrain and topography are consistent, it's still the default terrain and topography. Not sure that matters much to players flying over it so long as the seas and coasts are in the right place

In any event, it can be improved as we go along.
Only by making this have I discovered all the various campaigns that could use it, in the Adriatic, the Balkans, and in Russia. Currently adding the US 15th Air Force bases in Fogia Italy, and setting up the Ploesti Romanian oil refineries.
I hope it is easily translateable into 1.6, where it can use Ray's new East Front plane sets to good purpose.
