I've recently adopted the Fantasy Craft rules for my new campaign in the Realms. I think it suits better my party's need for roleplaying than the 4ed mechanics.
It was was quite easy to model the major changes brought by the Spellplague with this system. And I must add that I'm enjoing this adaptation work a lot...
There are others interested in playing the Forgotten Realms using this system? There are others that maybe already started using it for FR? Resources?
