wait KOTOR 2 is on the list but not the first one?
Uh... yeah. Because the second one was superior to the first in almost every way.
I actually enjoyed much of KOTOR 2 more than the first one, but if I remember correctly the story itself was weaker than the first one, mostly due to the game being rushed and a lot of cut content
It was only weak because of the unfinished ending. But once you learn about what the ending was supposed to feature, you see what Obsidian was building up to, and it's glorious.
The first game was typical BioWare ho-hum drama, save the universe, be ultimate evil or divine angel. The second was morally grey and ambiguous. There was no clear choice in most situations, and Kreia often chastised the Exile for making a light side/dark side decision.
