I dunno if that's good or not. I mean, the first and second trilogy don't have any characters in common besides Obi Wan, Yoda and Darth Vader + Sidious. There are some appearances of other chars, but very short and you can count them with the fingers of one hand.

I didn't forget Yoda. But you're right about the droids.
Also I think you mistook episodes II and III.
Anyway, they could have done it much further in the future. Not that I want that, just that it would seem more consistent between trilogies.
