I disagree. It's not hard to program AI that adjusts to what you, the user, are doing. NFL 2K had AI that adjusts, and that wasn't next-gen, for crying out loud!
Have you played winning eleven? It's impossible to score every time or even most of the time, because the computer adapts. There are no money combos or plays, there's no one way that virtually guarantee a goal. And if you score more than once on the same play, the AI adapts so you won't do it again, unless it's a lopsided matchup like Arsenal vs. FC Crew, in which case the computer can do nothing but watch Henry shred through the defense and loft one in past the keeper
, but that's beside the point. Adaptive AI can be programmed into a video game.
And as to your point about the Sim player not running it all the time, what are we supposed to do? Eliminate comeback routes from our arsenal? Or how about quick slants? Those are way too effective as well. So no comebacks or slants. Or posts. The receiver is in front of the defenders almost every time, and it is way to easy to gain big yardage. So no slants, comebacks, posts, or long streaks. Those are also money. In fact, why not just run the football. Oh, wait, running inside is too easy, and running outside usually results in a loss because the wide-receiver misses runs past the defender, failing to block him.
The fact is, you shouldn't be restricted from running a certain play because it works every time and be told that its your fault. Why do people refuse to blame EA? This is the reason the game changes only slightly each year. The users are blamed for their mistakes, and people who point out flaws in the game are flamed.
Maybe every post should be "OMG! EA IS TEH R0X0R! THIS GAME IS PERFECT! R0X0R!" But the fact is, EA has made a flawed football game.
It's still a fun game, and I still enjoy playing it, but it's not my fault comeback routes are guaranteed success.
The blame lies solely with EA. Defend them all you want and blame the players, but if you do so, EA will never learn.
