I'm beginning to think that the writers for Respawn, who did the two video games _Star Wars Jedi Fallen Order_ and _Star Wars Jedi Survivor_, were thinking very much along the same lines as Rian Johnson in _Last Jedi_. The two video games take for granted the destruction of the Jedi Order and the corrosive effects of despair and the desire for revenge amongst the few Jedi survivors of Order 66.
The Luke Skywalker of _Last Jedi_ is very much of a piece with the tone of_Survivor_, which takes seriously the notion of abandoning the quest to re-establish the Order as an institution. To be sure, in the Star Wars timeline, the two video games occur after _Revenge of the Sith_ and before _A New Hope_, but prefigure very much the tone of _Last Jedi_--sans Rey of course.
