Playing a normal single player game makes it hard for me to analyse. Just too tempted to just press the enter button and advance to the next turn
So the big advantage of PBEM is that it forces you to take a good look every turn and especially in this 1v1 no ai case the demographics can tell you a lot. And I need that cause I havent played a serious Civ4 game for ages (if ever)
I'll post a picture of the map tomorrow. I need to do a dotmap because I have a settler out so that combines pretty well too.
