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.
You'll seldom see such dedication in a mod. Lots of work went into this and it shows. I've played earlier versions of a different "Restored Content Mod" and it was very broken and unfun. I've played roughly 14 hours of the game with this mod and I haven't had any issues at all. All of the restored content is great to see all of these years after I first played The Sith Lords.
This is by far the best mod ever created for kotor2. Cut content such as quests, dialogues and even an entire planet(M4-78) are still being restored after several years from its original release. I remember reading in an interview that the lead designer of Obsidian was impressed and thanked TSLRCM team for their effort. As for me, Kotor2 with TSLRCM easily surpasses Kotor1.
This improves the game 100% making it fully playable, and keeps you from banging you head into the walk, you should not play KoTor 2 without this mod. Many years, and a lot of effort make this game what it should have been, and not what broken, half done game we had to settle with.
Having played over 100 hours of Sith Lords restored content mod, in all 153 hours (Steam) give or take, I'd say I've had loads of fun.
