Examples of Artficial Brilliance in Platformer games?

Lately, I've been compiling examples of bad AI in platformer games for fun, but after a while, I realized that it was rather hard to think of any platformer games that have anything beyond rudimentary or bad AI. Have there been any instances where platformer games have good AI? Heck, are there even any pre-3D era platformer games with anything beyond basic AI?

I don't think there really is much room to have good AI in platform games. As they're one of the most inherently simple genres, enemies must be kept simple as well.
