All of that could be remedied with a change in design philosophy. Expecting the player to be the all encompassing Wunderkind just doesn't gel with realistic AI.
An example is Alien Isolation. The AI is actually very well designed, except for the leash that pulls the alien toward you. On PC that leash can be cut, and the results are amazing. The Alien actually has to look for you and when it zeroes in on you it is even more tense than before, as you can't predict it.
I don't buy it that good life-like AI isn't suited for games. I firmly believe that it's a general failure of game design.
Which mod is it that untethers the alien?
