I have Star Wars: The Force Unleashed for the Xbox 360. It's not the Ultimate Sith Edition. It's also the first game and not the second one. However, the search games feature only lists those two, not the version I have (Copyright date 2008).

Hey @morriscox, welcome to the site! Here's a thread that others have used for requesting games that are missing: http://www.completionator.com/Forum/PostList/6?page=10

I'm generally able to get games loaded within 24 hours and try to respond to the thread once they're added. I'm always happy to load new ones, so feel free to drop in as many as you need! I'll go ahead and queue up The Force Unleashed for the next load.

I'd say in this case, just chop "Ultimate Sith Edition" off of the first game. If I'm not mistake USE is just the same game with all the DLC included, like a GOTY edition.
