Desert of Desolation was retrofitted to FR. It was originally released as being setting-neutral. I'm running it now. It really is a very good adventure, though I think that a good-faith update---not a thematically loosely related "spiritual successor" to other IMO often overdone classics as the others have been, but one that keeps a good bit of the story and plot intact---would be in order. The supermodule version has some rough patches and annoying decisions (e.g., the whole "teleport people to Raurin" to force them into the adventure) and a lot of areas that could be explored/filled out, either by WotC or by writers online. It would make a magnificent levels 1 to about 15 campaign, although I ended up running it starting at level 8 with existing characters. I wish I'd thought of running it before establishing some things I'm running now, because I'd fill out a lot of the details myself. It's a great story.
