Well, in the game your on some moon after being capture killing a dark jedi. In the last scene Duku approachs you after seeing what have done, and give you (Bobba Fett) a deal. Thus this is who the clones where created from. I don't know the year this happened, how far it is from the movie but it also explains how you meet the shape shifter thing from the Corusant chase scene in the movie.
