I thought Bastila was best among the KotOR characters. All of them were extremely
well crafted in terms of background and general amiability (well, except for T3...) but I found the interactions with Bastila to be the most entertaining (with Jolee a veeery close second.
And seeing I always inevitably ended up as Darth Revan (even when I triedreally
hard to play LS) I like the dark Bastila twist. So much so that I usually change her alignment and put her in Dark Jedi robes as soon as I leave Dantooine!
