Now, before I begin, I have I been playing Civ since the very first one. I have always been a decent player, prince has never been an issue. Emperor level in Civ 4 BTS was very challenging for me to beat, although I did several times. I just won an emperor game, small map, domination, in 375AD, turn 129. 6 C cav, 1 GG from the honor tree, and I took over the entire world. This should not be possible at all. I find this to be very lame on the AI in this game. The first Civ I attacked was the Germans, they had an equal army too me as far as numbers. When he sent 3 archers into my territory, in front of his warriors, and I killed them all without a single damage point taken, I thought, what a moron. Then, I took his first city, and killed 4 warriors/3 pikeman, without losing a unit, I thought, crappy play. Then I took his capital, without even a single ounce of resistance, and I thought, just wow, are they really that lame? Then I moved on to the romans, who were ahead of me in science and resources. They had 4 iron tiles, 3 6, 1 2 in there starting two cities, and did not have a single lego. There 8 warriors were no chance to my 6 CC. 2 turns later, their civ was conquered. Then I went to the last opponent, the Russians. It was 300 AD and they had 1 military unit, and only one city. In the city they had spent the entire game building wonders that do not matter. Pyramids, Great Wall, Hanging Gardens, etc. The AI is lame, and broken. The basic mechanics of the game are good imho. However, you need to give the AI a brain, or players like me will be discouraged. Civ 4 BTS made me have to think at the high levels. This game is lacking that all together.
