I think it really is down to Lucas and his dislike of his earlier "unfinished work" as the seamless branching you mention Andy, must be an easy enough task for someone with his resourses. Totally agree with you Crash about the similarity with Star Trek now. The CG space scenes just don't have that chaotic low-fi feel the originals have. If he ever CG's the ROTJ space battle I will scream!Interestingly, he's at it again with the DVD release of his first movie THX 1138 This new edition is going to feature lots of new effects shots.
