People I Want To Write Like:
Robert A. Heinlein. Andre Norton. Steven Brust. Roger Zelazny. Patrick Rothfuss. J. R. R. Tolkein. Jim Butcher. Matthew Woodring Stover. David Drake. C. J. Cherryh. Tanya Huff. (Yes, Nigel Findley and Pratchett.) Wm. Shakespeare, and Pretty Much Every Other Classics Author You Care To Name. Carl von Clausewitz, Sun Tzu, and Miyamoto Musashi - who all wrote the same thing with increasing levels of brevity and clarity (but Go Rin No Sho is still my favorite.)
Random Guilty Pleasures:
Steve (and Stephanie) Perry - who write novels out of movies, and into movies - if you want to write something incredibly formulaic that might get picked up and turned into a cash cow summer blockbuster explosion-ridden something-or-other, you couldn't do better. David Weber - who is, compared to David Drake, a truly terrible writer, but I -do- want to see what he does to Honor next. David Eddings - who turned a simple hero quest into two quintets and two trilogies, plus two or three add-ons - as far as I know. Stephen R. Donaldson - who wrote something interesting, then wrote like he was getting paid by the word - and still made it interesting, even if I would have murdered the schmuck only a third of the way through the first book, and kicked his ass regularly throughout the others. Alexandre Dumas, père - who, let's face it, created a story factory, stole their work, used every possible bit of novelization tripe in existence up to date, but still made it fantastic fun to read, and almost impossible to not imitate in some way.
There are literally hundreds of others ...
