I think the long-term sales of the games you just cited is at odds with your opinions. At this point, Bethesda has made a name for themselves with janky, bug-riddled games with big story, that excel at giving the players a feeling agency. At this point that is Bethesda’s brand image and they seem to be just going with it. Like why would they bother spending more money to fix bugs and exploits that have become a signature to a lot of people? Also it’s costs them less to leave their titles unpolished and let the modders fix it.
