After reading this thread, I started to wonder... Are these sorts of threads showing up on GTA: San Andreas forums?
Anyway, I have an XBox and can't afford to buy a computer that would run Sith Lords. I also don't live in the US, so probably won't see either version till February. Even if there was a change of heart and the extras were released on Live, Broadband ain't exactly cheap here.
Because of this, I hope you'll forgive me when I say that I would rather there weren't any PC extras. Although I would be grateful if Lucasarts could work out some sort of deal to include the original KotOR's Live content on the SL disc.
