Extra dialogue lines not playing

I was led to believe (post #67) that once the game had been completed twice, extra lines would be played on the third time through (e.g. When you meet Atton he talks about being cut from the Jedi Knight game, or something similar), however, having completed it twice, light and dark, I can't see any difference.

The only thing I can think of that might cause this is that a third game was started before I finished it a second time. Also, in the swkotor2.ini "GameCompleted" is set to 0.

Well, that, or I've been led up the garden path.
