TSLRCM tries to fix to the best of our abilities the issues The Sith Lords had due to being rushed. Containing a host of restored content and fixes many bugs left inside TSL giving you the most polished and best possible chance to get the full experience.
So far so good. I can't tell what's the TSLRCM in-game actually. But that means it has integrated itself very well that it's no longer just a mod, but a seamless part of the game. The only reason I can tell that TSLRCM is doing its job is that I'm no longer experiencing countless of bugs...and the story seem to make sense now. This mod deserves no less than a perfect score in my book.
