Civilization 4

The first thing you’ll notice is that the AI is virtually retarded, even on Deity. If you are a typical player in all previous versions of the game and set it around the middle to above average difficulty, you will have a challenge ahead of you. In Civilization 5, the AI does dumb shit like move their archers at point blank range of your swordsmen or other similar units that instantly devour them. I’ve seen them try to take over a city with archers, which cannot melee assault a city, a requirement for conquering in this game. That’s one thing that they changed that I kind of like (a miracle), the concept that cities count as a fighting force in their defense and have an attack/defense rating and can shoot ranged (2 hexes away) at their enemies.
