well, right before war levels, those guys that sat at the top of the hill, and decided who could, and couldn't go to war... well they were successfull enough, for long enough, that they grew complacent. and for the most part, any one that wanted to attack another player, was instantly classified as a bad guy. it created an ugly enviroment for any one that actually wanted to play the war game. and peaceful players got to expect to survive with little or zero defense, while still dominating the charts.
this lasted long enough, that their where only something like a dozen real war players left in all simcountry. and the inevitable happened, 2/3s of them got together, and attacked one of the former Peace Defenders, and slaughter them, in a matter of hours... thats when the idea of war levels where introduced...
the basic concept of war levels is good. and the rules for them must remain strick, in order to have the desired effect. unfortunately, they effectively destroyed not only the war game, but the political game.
