France '14

The guy named Volcano mentioned in the second link is the same guy you may know from the eSim/SBP team. I know by personel experience that he is very helpful and patient if you have questions. You need to register to get access to forums and mod download pages. His map rework for Danube '85 for example is very well done.
The basic system behind France '14 seems to be comparable to that of Danube '85 which I am currently envolved in. If that assumption of mine is correct, it is very recommendable a game design.
