The Unfinished Business patch adds many missions back into the game that the designer's didn't have time to finish. Often these are items, conversations, and even entire quests that were intended to be in the game, but time and money constraints meant they were left out, despite being close to completion.
Thanks for uploading all these!
Lot of dead links everywhere on guides/sites for this game, was nice to find them all here.
