Really, I can simply say ANY game in which I have an AI buddy or buddies, said "buddies" are the most useless lumps of programming. If I'm not babysitting them and making sure they aren't using up all the ammo and/or health, it's taking care of all the enemies for them while they sit back, take a few shots, pause... pause some more, another shot... etc. And of course, if they die, well then Game Over for you, sport! You allowed natural selection to take its course!
The only exceptions to this rule being some of your secondaries in Mass Effect 2 and Fawkes from Fallout 3.
