I only just recently saw those books. I have not played star wars since... was it saga? No I think it was the d20 version after that?
They are good books: I really enjoy the system. And the artwork is astounding, worth it just for that.
And I believe Saga was the last d20 version, neh? I remember enjoying it but I've always felt that d20 is just ... not the appropriate system for Star Wars. Never really felt right to me. Not that it wasn't great, and there's like a million books with tons of stuff!
But I really like the product FFG put out, very faithful to the source and spirit of The Galaxy Far, Far Away.
