i will get this when it goes beta :) i love the period and there are so much possibility to do something with arma
and if you don't like trench warfare?
the african theather, vonn lettow and his campaign in east africa- 4 years of successful guerrilla warfare
the ottoman campaigns of the middel east and the balkans - we got the map for a med east area already :)
the eastern front of germany and austro hungary, romania and possibly also serbian fronts could be well covered by the original arma 2.
the italian front could also be nice to visit, rommel won some victories there that should be fun to recreate :)
