Arden: The World of William Shakespeare is a Neverwinter Nights mod created by the Synthetic Worlds Initiative at Indiana University. You can play it, but it's kinda boring.
Neverwinter Nights is out!!! After waiting 4 long years and wading through a fetid quagmire of let-down rumors and whatnot, I finally have a copy installed on my laptop right now! Run, don't walk to your local Software Etc. and see if they have a copy. Our local WotC didn't have a copy, and neither did our local Electronics Boutique or Best Buy.
