There is a small bit of intrigue here, imagine you get to a boss and think, 'this is impossible' but there is an ability to observe a ghost of your character taking the boss on in your gear.

Bare in mind as well that 'AI' has existed as a word in gaming for decades and has nothing to do with LLMs, surely this is achieveable purely with the gaming definition of 'AI' simply coding the PC also as an NPC that reacts to things.
