@static @vampiress It's an issue because we're not necessarily talking about the fidelity of the A.I. Behavioral Trees in a game, but the general description of...building those.

Like,it occurs to me that even though I was specifically calling out UE4/5 Behavior Trees and AIControllers in an interview last year when discussing how I would try and do automated testing of a tool (Involving using the AIController to act as go-between between test and execution, like WebDriver.),maybe I hit a flag-

@static @vampiress Two main reasons that come to mind why they don't "Learn":

1.) That's significantly harder to test that they don't learn some really odd behaviours;

2.) It's a lot of work that often won't be noticed unless you have the A.I. decide what it's going to do, and then communicate it with a vocal cue to the player (The Alien agent in Alien: Isolation gets around the vocal cue stuff by...not having to speak the language of the player.).

@static @vampiress With 2.), I'm reminded that F.E.A.R.'s A.I. was notoriously good at stuff like flanking - but it required marking a lot of the map up with markers so that the enemy characters could say "Great, we're going to flank the player" - but if the enemy characters didn't *say* "Let's flank 'em!", it... probably wasn't going to be noticed that it *was* using advanced techniques.

Or put another way; a lot of work for something that looks very similar to significantly less work.

@AT1ST @vampiress Which is basically pre-generated data for the decision trees.

Sometimes, I kinda wish I programmed these things for a living, TBH. It sounds like my kind of data-driven shenanigans. :) But I have to be happy reading about it and theorising.

@static @vampiress It does sound amazing, but from a User Experience standpoint, it just... doesn't really pan out.

Like, it's lower than the Star Ocean PA systems, which tend to be more opaque than most relationship systems (And at least up until SO3 as I understand, much more complex than other relationship systems.); unless players run the game scenario a second time they aren't going to notice it doing different things.
