Okay, as I will restate, consoles is not an issue in this post named "KOTOR 3?" which means this post will only really talk about the XBOX 360, so please, I beg you, no more console-fanboy crap.
TSLRP (The Sith Lords Restoration Project for newbies) is a project set out to restore the content that Obsidian left out of the game as a result of pressuring to release the game early. As TSLRP stated early on in their WiP notes, the content was about 60% complete, but some of it was completely unscripted. So far, they have done an amazing job on the alternate endings and the HK Factory. They also resolve all the issues that fans send in. So far they will not release each build to anyone but their faithful beta testers. Another team (currently shut down) called team bantha, set out to restore the M4-78 Droid Planet. They encountered problems in their team, but above all, that much of the materials they were given were incomplete. Many voicelengths were missing and same with the modules themselves. They were able to recover a few voice files, and the people from the planet, but too much was just left out.
