@kdfrawg The problem with alternate history is that so much of it is crap (see much of what Newt Gingrich has written). One of the best examples, on the other hand, was written by economic historian Robert Sobel: For Want of a Nail: If Burgoyne Had Won at Saratoga. It's written like an academic history book, complete with footnotes, endnotes, and references. Absolutely brilliant.
