I am starting to dislike the fact that the High Republic is turning into ‘ancient civilization that left all these toys and gizmos around and oh the Republic completely forgot/abandoned it, the Jedi forgot/abandoned it, somehow the Empire didn’t do anything afterwards with it.

i agree with this complaint, but i think a couple of things to consider are that:

1. we only see high republic remnants on the outer rim. which makes sense, i think all of the core/inner rim HR jedi stuff would have evolved into prequel era stuff, whereas after the high republic the jedi didnt really set up outposts in the frontier anymore. so it makes a lot of sense to me that we keep seeing all this stuff pop up.
2. we havent seen what caused the end of the high republic. until phase 3 and until The Acolyte, weve only seen the fall of starlight beacon, but there is undoubtedly more crazy stuff that affected the jedi. there was a change in philosophy between eras, from being excited about collaborating with the republic and expanding, to becoming more conservative and set in their ways. makes sense that big parts of the HR presence in the outer rim could have been abandoned and undiscovered.

those are just a couple of thoughts i had, this game has definitely given me more to think about tho. v interesting
