Most Impressive Game AI?
togelius asks: "I have the feeling that when developers make the effort to put really sophisticated AI into a game, gamers frequently just don't notice (see e.g. Forza). Conversely, games that are lauded for their fantastic AI are sometimes based on very simple algorithms (e.g. Halo 1). For someone who wants to apply AI to games, it is very interesting to know what AI is really appreciated. What is the most impressive game AI you have come across? Have you ever encountered a situation where it really felt like the computer-controlled opponents were really thinking?"
When I was contemplating learning video game programming, I was reading a guide that told you first to program a pong clone, and then a pac-man clone. Why pac-man? It teaches you AI. The ghost behavior is actually fairly complex. One ghost wanders randomly, another tries to get on the opposite side of the board from wherever pac-man is. The other two form a hunting pair: one tries to cut off your escape while the other goes for the kill.
I never thought that the ghosts would be so complex!
Computers are useless. They can only give you answers.

Well, one of the greatest experiences (And still is), AI wise, is Stardocks XXXX-type space strategy game, Galactic Civilizations 2. I especially like, when on easier levels, you do something, and the AI race sends a message "It seems that you are making a massive buildup for war. However, with this difficulty level, I pretend not no notice it until you actually make your strike." or something to that effect.
Ive noticed that AI is not designed to beat your next move but is designed to cheat you without the player noticing. Command and Conquer and Gears of War are two games that have two well hidden cheats. Command and Conquer is twelve years old almost, the enemy AI was programmed to always have full resources as long as one harvester made it back. Therefor what would take you five harvesters would only require them one. Most players would of never noticed this unless their strategy was to cut off enemy resources instead of an full out assault. Gears of War was praised for having AI that used the environment to their advantage which helped cover a little cheat they had. The AI had a weird tendency to know exactly where you were as long as your cross hair covered them or came close to them. For example if you were to pop your head out and just happen to have your cross hair on an enemy turret that was always firing at a covered friend, it would immediately start firing at you, this would also goes for the regular grunts/guards. This is very noticeable on "Insane", since that mode requires you to use cover 90% of the time and better tactics then rush in and shoot everything that moves. AI is not designed to outsmart/out think/or consider your next move, in my opinion most AI is designed to defeat you by using small cheats in the programming that give it an unfair advantage and hopefully designed so that you wont be able to notice it.
