Tutorial is great, I watched all. Great presentation wise, exactly the kind I like - not only every decision explained, but also future plans, alternate ways (and why you didnt take them at this particular situation), etc. It really helped me to learn a thing or two about errr a thing or two. Thank you
Now some questions. (I'm still struggling with the Emperor level, winning probably less than half games.)
First, diplomacy. You seem to be pretty much isolationist - closed borders everywhere apart from De Gaulle and Oranje. Why? I usually open with just everybody. I.e., in this particular case, what harm could come from opening with Hannibal or Darius?
Second, diplomacy. You stated that Oranje is a backstabber, declares at pleasant, and then you were trying to have good relations with him. Why? If he's a backstabber, why bother? I would have had him as my first target. So did you. That puzzled me even more - why bother with relations if he is gonna be wiped out asap?
Third, diplomacy. (yes, thats my theme... never quite learn how to do it). You said you dont care about Shaka much. But chances are, Shaka is right behind Oranje who's gonna get killed soon. In this case Shaka would be your direct neighboor. It really doesnt make sense that you wanted relations with Soon-to-be-dead-Oranje but not with Soon-to-be-your-neighboor-Shaka. Why? I know you cannot trust Shaka but still... if you have good relations with him, you can point him to the right direction and avoid being attacked yourself. Especially if you were going to war against another AI you dont want Shaka to join in against you or dow on you prematurely. What am I missing?
Four, infrastructure. You didnt seem to care about roads much, while I always connect every city just in a case I need to regroup my army fast (barbarians or unexpected DoW). Was that because you had not enough workers and other jobs seemed to be more important, or why? Is that normal strategy than you dont care about roads first hundred turns if you have rivers/coastline for trade routes?
Five, exploration. After initial search for places for new cities, I try to explore as much as possible, sending at least one warrior/scout/chariot. Now you had black tiles right next to your cities and it seemed OK. Do you always play this way, or its just particular circumstances, like having not enough units and desperately need them elsewhere?
