It's expensive, early attempts didn't impress, and many gamers are hostile to the tech because it threatens the livelihood of game creators and impacts gaming hardware prices.

IMHO at least 2 reasons, the jagged frontier (you cant easily evaluate the capabilities of your companion, I expanded a bit on https://news.ycombinator.com/item?id=49419952 ) and probably riskier in a lot of story games the risk of spoilers if the model isn't sandboxed properly, which I don't think is trivial to do as you don't know the training set which probably includes games and books games might be based on.

It depends on if you want samey games or anything creative.

You could have complex realistic dialogue for innkeeper #28917 in the little hamlet of ass backwards, but:

One: do you really want that? There is such a thing as too much realism in a video game.

Two: do you really want all NPCs in all games to speak nigerian business english?

Why would anyone want to have an LLM generate content in a game when people can barely stomach it generating awful pictures and generic prose?

Who would want to have a non-deterministic, unreliable, out-of-your-control companion in a single player game?

What kind of game designer would find it acceptable to have no control over large swathes of their own game? Who would like to play a game that no one really created?

Games are where art meets engineering to create entertainment and awe. LLMs don’t fit.

at the current token prices, far too expensive, but in medium/long term I think we will see a revolution in this field, the concepts are already there (and the expensive proofs of concept already work)

Because games are entertainment, but outputs generated by current AI are rage inducing and felt hostile, not entertaining. It just isn't past the "make it work" stage.

It did, look at the game Suck Up or a variety of Skyrim mods. Problem is gamers are hostile to any obvious trace of IA in their games. Also, consumer hardware is overall too weak to run a convincing llm model.

I'm especially interested in how this can be applied to the world of the game. I think that creates much more interesting results than NPCs who can hold dynamic conversation. Imagine an MMO where quests you complete actually shape the world (its landscape, structures and enemies). Then dynamic quests can be created based on the new world, creating a living loop.

LLMs have only been really good for a couple years. You can bet that the remaining AAA studios are working hard on figuring this out in current unreleased products.
