Supposedly, the Great Wall is supposed to make everyone offer you peace. I was at war with two other civs and got a great builder, and I thought "it'd be nice if I could focus on tech instead of military for a little bit, I should use the Great Builder!" Well I built the Great Wall, but I wasn't offered peace. The other two human players were still at war with me and I couldn't get peace; I wasted the Great Builder on an absolutely useless Wonder. Nobody had engineering yet so it wasn't obsolete. Did I miss something? Otherwise the Wonder shouldn't even be in the game.
