Nah I'm pretty sure the gungans and Naboo were just added into that last scene on these releases. They did do a big overhaul of Cloud city and add tons of Corascant though for the 97 releases.
As against all the changes as I was when they first happened, over the past few days I watched all 3 films and the big doco, and I think I'm starting to turn to the dark side. I dont mind the changes so much as I used to.
I think the only things that really shit me are the change to Boba Fett's voice, and the stupid little comic relief gags that were added just to insert CGI elements. Like at the start of A New Hope where they drive past, and then some droid just bashes another droid out of the air. Totally wasted screentime. Theres a bunch of things like that...they dont make me hate them, they just annoy me a little.
I think what makes me not mind them so much now, is how awesome the DVD transfer looks. Its so vibrant and awesome. Film -> Digital Colour Grading -> Film -> DVD is great. Thats how Lord of the Rings was done, and that looks amazing colour and depth wise. The old Starwars movies have that sort of look to them now, which is cool. Its a shame that the newer films were just all digital and look like puss.
But yes...the darkside is being very seductive and quick to turn me to not minding these changes and alterations as much as I thought I would. I thought I would buy these DVD's and just sit yelling obscenities at the screen the whole way through, but it didn't happen. Even having pussy boy's face instead of the other Anakin guy (sebastian shaw?) at the end of Jedi wasnt that bad really.
The Empire of Dreams doco actually gave me a lot more respect for Georgy boy. It's a great watch.
