Maul's presence in the first game was completely unlike that because he was a character from the films, so it was semi-acceptable (once you get over how random the encounter was, but I guess that's the point). Encountering Naga Sadow's holocron just would not jive with such a game. If the franchise had been very heavily steeped in Expanded Universe lore from the get-go, fine; but it was intended to cater more to the movie crowd.
You get me?
Yeah, actually you make a good point. They made up alot of material for TFU instead of using the EU. So that actually makes sense.
