After hearing about Dark Sun, one thing I wish WoTC would do is a 'rerelease' of the Forgotten Realms as it was initially with some of the better stuff picked for paragon paths, etc...
Me? I'm playing 4e set in 137X (3rd ed timeline.)
Agreed!

I loved the very 1st Realms boxed set, to me
that is the Realms, not the..."Elminsterized" version we ended up with.
I don't like the 4th ed version, not because it's bad per se, but because of the incredible artificialness of what was done to the setting.
The "Time of Troubles" just to fit the 2nd ed rules in....*barf!* no need of that. and Cyric especially = complete loser as a deity (and that's a word I normally hate to use, but he is a complete drivleling non-entity gets to be a god and makes a mess of it and goes nuts...ah huh! You really think Ao would let that twerp keep that position AND cause all the trouble he has?)
It's like, any time there's a major change, they take it out on the spellcasters in the Realms....which I feel is grossly unfair and a nasty Deus Ex Machina.
High level NPCs weren't the problem, it was having everything mapped and over populated to heck...there was nothing "Forgotten" about it, nothing wild and mysterious...where as the 1st boxed set, was.
Also as I've repeatedly said, the 1st boxed set is beautiful, look at the artwork, it evokes a feel of a far more rustic, wild world.
Richard Baker's "Swordmage" books paint a really good, interesting picture of the new Realms, by the way

So I just think it (change to 4th ed Realms) could have been done better.
