Enemy AI is a difficult subject to tackle in video games. Some may argue that current tech isn't advanced enough to implement ultra realistic AI. However, in a world where your phone's AI can book appointments for you, can't it spot a hooded figure hiding in a 'crowd' of four people? In fact, the AI in 2006's The Elder Scrolls IV: Oblivion was so smart that the developer had to 'dumb' it down for the final release.
The story says that each of the thousand NPCs had their own needs and wants and that was what determined their routine for the day. One story often told is that one NPCs AI determined that it was time to rake the leaves, only the nearest rake was in the possession of another NPC. So the AI determined the easiest way to get it was to murder the NPC and take it from his corpse. Five minutes later the player wanders in and there's a dude raking leaves and a corpse in the corner, the player wondering what the hell just happened.
Hence, AI is a tough nut to crack. Make it super realistic and the game won't be fun anymore as it's too tough. Make it too dumb and, once again, the game won't be fun anymore but this time because it's too easy. A "good" in games are not "good" AIs, but an AI made to look good or simply put.
Now we know that AI is difficult, let's add the dynamics of the open world to make it a bit spicier, like a fended environment such as the spaceship from the Alien Isolation. Simply put without diving into the logic of the AI, the Alien AI was familiar with its surroundings and knew what to based on limited user inputs. However, in an open world where there are multiple approach angles, many ways to infiltrate and various approaches to eradicating your target, a "good" AI is all the tougher to achieve.
