I thought the tie between the trilogies was great. I was confessing failure in the guessing game.

Before ROTS, the game seemed like "pre-plagairism" that, in the very unlikely event that there was some shred of truth in something, could be a spoiler for some people.

In my SWU conception, the DS was not an innovation, it was the first time that a galactic power could pull together the resources (through confiscatory taxation and pillaging) to harness such planet destroying energy. (sorta PT)

I tried to work 3PO into the history (not so much R2. He seemed new, but I suppose "new" could be very relative in a "timeless" U.) I thought there might be some kind of security program that automatically flushed his memory of compromising info about his former masters the moment he is salvaged or purchased by others (why he knew about the princess, then didn't) After ROTJ, I thought he might have been owned by the mother's family for several generations (Lady Jessica/Princess Leia.)

I thought the new R2 might have limited hover capability. Avoids draining power cells.

I thought non-hyperspace capable fighters would be launched from pan-galactic warship "carriers".

That's all I can remember about PT tech. :)
