I think that all of this could be implemented iff CA released the hard coded information. Although I see nothing wrong with doing this with a six year old game, CA could see it otherwise. For instance, let us say they do so, you implement your homelands (very good idea by the way). Some one else implements an even better diplomacy system. Someone else improves the AI. Another person somehow manages to improve graphics (don't see how this is feasible, but maybe?). We now have arrived at a superior game to either RTW or MTW2. This could potentially kill those games sales. Of course I may be wrong, and half if not all of it is opinion.
