Age of Civilizations II Guide

Seeing as I made the guide on how to play this game, I thought it made sense for me to challenge my skils at this game by playing it on the hardest settings possible. And, so far, after 10 attempts, I've finally figured out how to do it without dying before turn 200.
This is my current progress in my test game:
This is a game where I played as Tunisia in the Modern Day scenario. Of course, it was on Legendary difficulty with the AI being 4 times as aggressive. I've died trying this many times. Italy killed me, Algeria killed me, and Malta invaded. It's a difficult thing, but I managed to conquer the western coast of the Balkans in 100 turns, turn Tunisia into a rank 43 nation from a rank 88, and ally with Turkey, a rank 17 nation. How'd I do this and how can you do this? Well, it takes luck, but there is a lot of planning involved too. Let's get started.
