The race is going well so far.

I'm in first place, I've dropped a couple of scorching laps times, and I've got three red shells for protection. No one's getting past me.

Well, until Donkey Kong does.

That's OK, though. I nail him with a red shell. Off he tumbles. I'm back in first.

Five seconds later, he passes me again.

Another red shell and another 10 seconds after that, he's flying past me. This time he's firing a shell of his own, and I fall all the way back to sixth place. I can't recover in time and finish fourth.

Stupid monkey.

Look, I understand that the computer has to level the playing field somehow, because I'm just that good. But the Mario Kart series is a prime example of how some computer A.I. programming can go from keeping every match competitive to causing blind, controller-tossing rage.

I asked the Bitmob community on our Twitter and Facebook accounts to give some examples of the most egregious offenders in this area, and here's what they said:

Street Fighter 4 (suggested by Cesar Gamboa and others)

I got several responses naming other fighting games, but Seth, Street Fighter 4's final boss, took the cake. With special moves from every character and juiced-up abilities in Arcade Mode, this weirdo has ended many a World Warrior's tournament.

Puzzle Quest: Challenge of the Warlords (suggested by Rambo Higley and others)

How can a computer cheat in a match-three puzzle game? By getting ridiculous, impossible-to-predict combos, that's how. Opponents in this game will make seemingly illogical moves that chain into a cascade of four- and five-of-a-kinds, granting extra turns and bonuses galore. Twenty turns in a row and you're dead before you even moved. Yeah, that's cheating.

Call of Duty: Modern Warfare 2 (suggested by @sm4kxd)

Facebook user Jon Shults mentioned, "Any recent first-person shooter on its hardest difficulty gets pretty cheat-y." He's right. And the Favela map in MW2 is Exhibit A. Enemies tag you from rooftops from miles away. Gunfire blasts from cover areas you just cleared out. And everyone seems to be psychic, since they all know where you are instantly, even if you're hiding.

Madden series

This can depend on your difficulty setting and skill on the sticks, but every Madden player can tell horror stories about games where the computer just decides, "You're not winning this one." Inexplicable fumbles, broken tackles, and circus catches ensue.

A few other suggestions I received:

@willikampmann: "Easy: Dead Rising. Most retarded AI ever and you have to depend on it."

@GamingInsurrect: "Cheapest A.I.? Try Jinpachi from Tekken 5 and Azazel from Tekken 6."

@feitclub: "Mortal Kombat A.I. was always cruel. Would often throw me at impossible times."

Aki Darwich-Mcfadden: "The Polygon Fighters in Super Smash Bros.!"

Michael Wenzel: "I vote Eye of Judgement on the PS3. How do you magically draw every card you need to win? Heart of the cards bull? Cheating whore."

Jennifer Dremmers Taylor-Foster: "The psychic guards and such in The Elder Scrolls 3: Morrowind. Even in another building they'd know something had happened!"

Ken Wesley Jr.: "Streets of Rage 3 on normal difficulty was insane due to the A.I. enemies moving unbelievably fast on later levels, making a regular hit impossible."

So which game has driven you the craziest due to unfair A.I.? Let's hear it.
