Sure there's a real difference in the medium as far as the writing is concerned but the storytelling? If anything the novels are less demanding as he can exhaust all of his time and effort into a single plot rather than having to branch it through a variety of choice driven alternating paths. Also are you sure that he has a team of writers working with him on the mentioned games? I was under the impression that he was the only writer they hired for those specific games (and almost certain as far as KotOR's concerned), the upcoming MMO excluded.
