The whole idea that people couldn't run the Forgotten Realms because it had too much detail or lore is just a cop out. You're the DM. Run it like you want to. Besides, the Realms was big and diverse enough to find plenty of place to be your "sandbox" if that's want you wanted. Why can't people be honest, and just say they don't like the Realms instead of acting like their hands are tied by the "massive amount of FR lore" so they couldn't run it.? Talk about hyberbole.
I think you could give the "light touch" treatment of 4E's description of things in FR without having to include the world-altering events of the spellplague. The spellplague was simply an unnecessary event.
For example, Silvanus? is Sylvanus of Celtic Myth, because the original campaign used Deities and Demigods to develop cultural areas. Sharess was Bast! Loviatar was..uhm.. Loviatar.
Compare the reviews of the 3e FRCS to the 4e FRCG even on just Amazon two years after the latter was published, the difference is pretty stark even when you remove any negatives that are poorly explained rage, or similarly poorly explained adoration.
Not how I recall the 1e version at all.
They're still mainly fanboy reviews and not worth much as an indication of anything.
yes, seriously.
