Is this the game you mentioned before where you are playing Rome?I retract my statement of Great Generals being useless. I of course never meant it that harshly, but chosing that for faith purchases over Engineers or Writers?? Well I'm taking another look at this.
I'm doing a very war oriented game right now. And overabundance of citadel's certainly wouldn't hurt, however I chose Tradition. I like how the AI is a little more smart in VP and won't keep walking directly into citadels but they are certainly very useful. If you choose authority domination is most likely what your would be going for. So the great generals would probably be quite useful because in the end a cultural victory is not your goal...
Rome gets crazy amounts of great generals as part of his bonuses. For normal civs you appreciate each general you get a lot more.
