This is an incredible find! I've found hours of content to keep myself occupied this entire day, and I've only done Korriban and Tatooine!
I am quite content with a large amount of side quests that don't serve a unified plot line. At least, beyond the commonality that they relate to the aftermath of the Jedi Civil War.
KOTOR II, as I've read it described, is essentially a "road trip from hell to absolutely nowhere, all the while pondering the void". To quote the cliche, "it's the journey, not the destination". This game is actually perfect to use for myriad narrative vignettes that are seemingly unrelated.
I look forward to playing more, and seeing what you may add! Keelah se'lai
