I have to give direct credit to Greenwood and this tendency of his for helping shape the way I still game to this day. I never played in the Forgotten Realms, but I've always embraced the way he treated the setting like a real place, with history and cultures and villains and heroes. Sprinkled with a bit of Lovecraft's more casual attitude towards setting detail, it can really make your worlds come alive.Having reread my old Dragon issues a couple of years ago, I was definitely struck at Greenwood's facility for using extraneous details to give the impression of a larger, living world. I can't say that I'm that fond of his overall worldbuilding or other storytelling elements, but he always has impressed me in generating interesting psuedohistories and flavor in his articles and settings. Sometimes it does result in silly levels of detail (did we really need to have articles on all the types of trees you can find in Realms' forests), but it does good things for verisimilitude.
