I can hear it now, OMG A MOD IS CRITISIZING MK:D FIRE HIM. Hush up. I think this is one point of MK that is gonna get more support than any other critique. Face it, MK has never really had good AI programming. Either it's too easy or it's too hard, or the AI doesn't act like it should, either too offensive or defensive. Let's look:

MK1 - This one was a major pain to beat. As you got up the ladder, more of your attacks get blocked and countered, and the AI almost did nothing much unless you got to Goro, and even then keeping him down was tough. Tsung had the only major weakness in that you could learn when he'd morph, and attack him then. Otherwise, you were stuck trying to force the AI to make a mistake, when they don't do much to being with.

MK2 - If it wasn't for the jumpback trick, this one would take the cake. Unfortunately, they made it so that no only does the trick only work on the Player 1 side, they attach it only to certain characters. Liu Kang, Kung Lao, Kitana, Mileena, and Raiden did not get it. Therefore, if the difficulty of your opponent is high, you get raped. Especially against Liu Kang and Mileena, who if you wanted to jump kick, you'd have to do it at the exact right distance so that they would jump to throw a projectile at you, but your kick knocks them from the air. Play the game on Very Hard with these characters and you'll see. The AI's sudden duck-uppercut in .0003 second move is annoying as well.

MK3 - This one actually had it where it should be. The AI was offensive and defensive to where it was a challenge, but it was still ridden with bad methods. Even with the game on Medium difficulty, play the Master tower, and it's still a pain in the ass. Liu Kang having a triple Bicycle Kick into his 7-hit combo in the corner move helps none. If the AI stopped with that, then you'd fine that the AI was also stupid. Let them run at you, roundhouse, and repeat. It never ends. They could've just removed that and left the rest, but they decided to ruin it completely with...

UMK3 / MKT - Un-freakin-believable. Never mind the fact that the AI is like MK2's in that the AI counter's almost everything like it does, without any flaws (aside from the trick to repeatedly trap them in Sindel's scream), but that they stay the same distance from you, moving side to side as you do, doing nothing until time runs out, or if you get too close or do nothing for a few seconds. Talk about awful gameplay. I thought the game was "Kombat", not "Keep Away". Just makes the game extremely boring when you're restored every match to win by time out, almost never seeing any action, and almost never getting to pull off a finishing move.

MK4 - This has to have the worst AI ever. This AI doesn't even try. Not even on Ultimate difficluty was this game anywhere near hard. Just constantly run in and do the same damn combo over and over. The AI always lets go of their block, and gets hit over and over and over and over and over again, without even trying to fight back. There's just no challenge in this game, period.

MK:DA - This one had just as boring AI as UMK3, and the slow speed of the game isn't even a factor. Set the game to Max difficulty, and the AI does almost nothing. When they do, you can easily block it and combo in return. Since that's all you have to do, there's almost no action because there's almost nobody getting offensive. And with just one major branch combo per character, which is probably what most people use against the AI, you see the same thing over and over and over again. Oh, and the AI's abuse of reversal's is annoying.

So really, if you're gonna make AI, make it so it does something, and when it does, give the person playing some leverage to play back. When I play MK:D, I want AI that's good enough to give me a run for my money, but I also want to be able to become good enough at the game to where I can be its equal. None of this over-offensive or over-defensive BS.
