'Star Wars,' 'Doctor Who,' 'Forgotten Realms,' even 'Firefly' and 'The X-Files' have shared world novels and other media. I can't help but notice these settings have large shelf space in bookstores, so their publishers and authors are getting something right.

I don't collect the way other people do. Some people collect rare guitars, like, 'I have a '54 Strat worth $50,000.' And I don't collect the way Nash does. Nash has Duane Allman's guitar and Johnny Cash's guitar. I bought guitars because they sounded good. I played them, they sounded unbelievably good, and I couldn't resist.
