Best PROGRAMMED videogame enemy you've faced?

[PxDn Ninja]

That zerg computer player I faced on Starcraft a few months ago.

Not only did it exploit all my unit weaknesses and use spells with uncanny accuracy and skill, it also set up a complex ambush that annihilated my entire army.

Blizzard just uses a script based AI system for their AI, rather than a true AI algorithm. Not saying this is good or bad (though I have my opinion on the matter), but just stating that it is not really a programmed AI. More a scripting design.

For me, I would really need to sit and think about it to come up with truly brilliantly programmed AI. Off the top of my head I can't think of anything.

Seymour Guado on Gagazet in Final Fantasy X. No video game enemy has ever given me as much trouble as he has.

I have to agree with this.

He was an ass to beat and just didn't die. Also, some of the enemies in the Ratchet and Clank series put up a good fight though not many.

In a way the foes in Ninja Gaiden 2 have very good AI. They don't care if you are in a ultra combo, if they see a weakness, they will use it. As it should be. Looking at you Assasins Creed....
