I don't have a lot to say about this one. For anyone who is not familiar with Neal Stephenson, he seems to write books exactly for me. Super geeky and often epic in length. Cryptonomicon included a Perl script and the Baroque Cycle numbered about 3000 pages. I've read all his novels. One of the main plot devices in Reamde is a fictional MMORPG called T'Rain. The book was awesome and I loved it but it certainly wouldn't appeal to everyone.
