Diplomatic AI seems to be improved (or not depending on your point of view). That bitch from Egypt declared war on me and in 20 turns I was gone.
Need to do things a little different in 6 I think. I usually work on the infrastructure, and looking at the big picture. But I think I need to work on defence before anything else first, in 6.
As far as total war goes, I turned off the game after the first Medieval Total War. That game still remains my favorite. I really don't like the modern 3D/Live map. Don't know why, I just didn't like it. Disliked Rome:TW immensely. Tried it a few times since, still hate it. Just one of those things.
