Halo 4

From personal experience uncharted 3 which was very inconsistent.

Tomb Raider (2013) is pretty awful. Even during the shootouts later in the game I just could walk calmly towards the enemies and give everyone a headshot with the pistol once they glimpsed out of cover. Same thing in GTA IV. 3rd person shooter AI just doesn't work with the superior accuracy of a mouse. The supposedly weak pistol becomes the best weapon in those games on PC every time...

The Last of Us AI was...... let's just say not very good.

I have been hearing the opposite........I never played it so I don't know.....................

Skyrim dragons. Half the time they don't even acknowledge the players existence. They run off and kill random npcs or sheep instead even though i'm shooting at it.

It's just my opinion. When I stand right in front of an enemy and they don't notice me I would call that stupid AI. 

You people should play moar games:

Resident Evil 5 was unplayable without a second player.

Resistance 2. It was so bad that my roommate thought I was bunkers for talking up the first game in the series. Thankfully, he was able to borrow Resistance 1 from my brother. R2 had 90s AI. Whether they could see you or not the Chimera knew where you were. They completely ignored your partner and ran right for Hale.
