The 100 Greatest Science Fiction/Fantasy Novels of All Time

Glad to see Rama's there.
Personally I'd add 'Olympos' by Dan Simmons, just because like the idea of flipping myths into sci-fis, but 'The last starship from earth' contains some of the best written scenes I've ever seen.
However, in my view, the best sci fi ever is, without a doubt, (if you allow short stories, it's All The Time In The World by Arthur C Clarke) is Stephen Baxter's The Time Ships. Better than the original. that being said, i also love Asimov's 'The Positronic Man'. Who wouldn't?
