The version I read was the original paper back. I read it back in the 90's. The movie tie-in; I've not had the pleasure yet. I feel some trepidation after seeing the first big screen version of "DUNE" back in the eighties. I thought the screen version of that book was the remains of a slaughtered short story that Frank Herbert would not have signed after I read the full version. I think CGI has come far enough by now that there shouldn't be any unwarranted blood on the cutting room floor. I do look forward to it.
I have the dual benefit of having been raised Mormon, but no longer a believer. I love his novels, and everything else he's written, from short stories to WorldWatch on Ornery.org to "Uncle Orson Reviews Everything" on Hatrack.com. He is, quite simply, my favorite author, and I have a lot of respect for him. I don't always agree with him, especially about social issues like this one, but I have read the article in question, as well as some of his others. Here's what I think: he is against gay marriage on a personal level because of his religious beliefs, while generally, he argues that the government is using authority to force this re-definition where it should have none, and that it is a dangerous precedent to allow it to happen this way. He makes sense, when you look at it that way.
Anyway, here is his most recent blog regarding his (and the Mormon Church's) position on Proposition 8, posted today, Oct. 23, 2008. In response to the OP, he writes:
"We do not think that any belief system, whether it calls itself a religion or not, should be imposed on other people by law -- we won't impose ours on them, and we won't let them impose theirs on us or our families.
Instead, we believe that as long as we are citizens of a free country, changes in the laws and institutions of our society should be made only by common consent, after a free and candid discussion."
(Oddly enough, I don't support Prop 8, but I appreciate his rational discussions on the subject, where he at least has a better argument than, "This is what we believe, so there." I understand his opinion, and it makes sense, but I'm still not convinced he's right.)
Edited to add: This is the quote that stopped me in my tracks, from the same post: "In fact, I believe that even those who absolutely believe in gay marriage should join us in opposing any law that is forced on an unwilling majority by the dictates of judges. For those that are wise will recognize that once judges are given such power, that power has as much chance of being used against them as for them."
One thing no one seems to take into account when discussing Ender's Game is WHEN THE BOOK WAS WRITTEN. You must consider that, when this book was written, we didn't HAVE laptop computers, or three-dimensional video games. We did not have the internet; at least, not in the form that it is today, and not nearly as accessible. The nets and the computer "desks" that these kids had are commonplace now, so when you read it, it suddenly just feels like a story. A writer's ability to make superior technology and alternate future casual and commonplace is one of the main things that makes science fiction good. This book had that in spades, while bringing a true human element and empathy into the mix. I was engaged from the start and enjoyed every moment, and was even disappointed when the book came to an end.
I'm 41. I love Herbert, and Asimov, so I don't feel that the "science fiction level" of a book is at issue in any way here. A good book is a good book. I'm in agreement that a book should be read, and not heard, and that it makes all the difference. There's something comfortable and intimate about print, which is why it is so difficult to make a movie from a novel that captures its true essence, even from person to person. It must be even that much more difficult with nothing but a voice.
You know, truthfully, I'm not sure. I purchased this book for my 14-yr. old to replace an old copy of Ender's Game that I gave to one of my older children. I haven't even looked at this edition. Maybe you can tell by comparing the table of contents of a couple of different editions. Hope this helps!
