You seem to view the only way computer games can be enjoyable is aa tightly-scripted near-movies. And that's certainly one model, but hardly (even without LLMs) the only model that has proven enjoyable. LLMs potentially (I think they’ve got a wat to go before this is really viable, but the potential is there) open up new styles of conputer gaming.
It’s not really new. It’s just a social role play without the social aspect. Which is worse.
Games don’t need to be near movies but they should have an either a cohesive plot or no plot. A shitty made up on the fly plot is just not going to work
