Star Wars: Knights of the Old Republic II - The Sith Lords (2004)

Kreia is the companion for anyone who has wanted a mentor to question the kindly option as fiercely as the cruel one. Atton and the rest of the crew have their own guarded perspectives, revealed through conversations and influence. Expect older systems and an uneven, abrupt final stretch, but plenty of arguments that resist a neat light-or-dark answer.
