Hehe, take a look at the AOTC and ROTS pages and tell me if those are enough...
And yeah, I agree with you about the tying-up the loose ends, I made a clear point of that in the ROTS intro. I tried to take care of that through some of my changes. Take a look at the last one, the alternate ending. Although I think it's impossible to be made and I'm not sure if it would really be effective, but I think it logically takes care of the the things that have to be tied up.
As for the OT, yeah I know a lot of the changes a bit too much, but some are pretty much mandatory. Like lightsaber effects, etc.
