I think you underestimate us. We have already created the new faction, including all the models, we aren't just starting out. We have a large, talented, committed development team who have been operating for over two years.
Our reference for realism has been a combination of period photographs, actual blueprints, Soviet and German accounts of the war etc, not other games. In fact, we have several dedicated historians on the team.
Since when did a mod have to be basic? We can create a 'new game', so we are creating a new game
