On a very general level, I disagree that the game mechanic should reward the more balanced playing strategies as if they were superior to other approaches. If I have for some reason failed to get culture early on and plan on a big war and then somebody resigns, it is kinda rude. The point of the game is not to have the best economy, the point is to end up with more culture than others. If, in the meantime, someone gets run over, it is often poor judgment in keeping up with military. So overall, a better mechanic in war resolution when somebody resigns mid-war would be great. 7 seems quite low instead of say 40-50.
