Do you plan to read Blue Mars and Green Mars? I read the trilogy way back in the early '00s and remember enjoying the series, although I was young and some of it could be confusing (and sometimes boring). What did I expect? The series is hard science sci-fi, and, therefore, difficult to understand at times. I remember feeling smarter after reading it! Ha ha. One of its problems was lack of action--or not enough. It is a thinking man's science fiction series, for sure. I do think the entire series was worth reading. Arkady was a great character, I seem to remember.
I have periodically wondered if I should reread them, but then I think about all the books I haven't read yet. I'm already rereading another series of books, so Robinson's books will have to wait for their reread.
