Try this as a way of looking at the Grand History of the Realms:
- The Arcane Age Setting (all Arcane Age rules in effect) - Covers all the time from -100,000 DR (the end of the Age of Thunder and the Time of the Creator Races) to the Fall of Netheril
- The Fall of Myth Drannor Setting (modified Arcane Age rules in effect) - Covers the time from the Fall of Netheril to the Fall of Myth Drannor, a time in which the use of High Magic was truly deadly
- The 1st Edition Realms (all 1st Edition rules in effect) - Covers the time from the Fall of Myth Drannor to the Time of Troubles.
- The 2nd Edition Realms (all 2nd Edition rules in effect) - Covers the time from the Time of Troubles until the End of the Elven Retreat and the Rise of the Dwarves (the dwarves start becoming wizards.)
- The 3rd Edition Realms (3.0 and 3.5 rules in effect) - Covers the time from the Rise of the Dwarves until sometime during the Spellplague.
- The 4th Edition Realms (all 4th Edition rules in effect) - Covers the Forgotten Realms from sometime during the Spellplague onward.
So, for example, for around 95,000 years, you had to deal with assorted ways of casting magic (elven, Netherese, Imaskari, Djinn Calimshan, etc.) and 10th and 11th level spells could be freely cast. And there were *Archwizards*, super-mages who could throw 40d6 fireballs.
After the Fall of Netheril, no more 10th and 11th level spells (except for elves, and only 10th level for them.) Elven High Magic is deadly to cast, but less so as time wears on.
A 30th level wizard, like the Simbul, could still throw a 30d6 fireball, since no caps existed on spells.
No more 10th level spells. Period.
Enter the Time of Troubles. After that, assassins worked differently (if they worked at all) and your fireball was limited to 10 dice, along with many other spells.
Enter the 3rd Edition world. We have new concepts such as Prestige Classes, so history must be subtly rewritten (it makes sense that they were always there ... a Purple Dragon Knight was a generic cavalier or fighter; now he's a Prestige Class with his own abilities.)
Enter the 4th Edition world. Things are new and strange. All the rules are different. People remember how the Old World worked, but it sure doesn't work that way now.
That's over a hundred thousand years of Realmstime to play in, and just one FR setting out of countless Alternate FR Settings (for example, one in which the Chosen of Mystra are less powerful and influencial than they are in the Canon, as is desired by some people. Or perhaps one in which the Red Wizards of Thay are intelligent, organized, united, and a real threat to everyone else.)
You can pick and choose your timeline, and in FR, the timeline determines the rules! (If you allow it to.) Don't like the 2nd edition rules? Go to the 1st edition timeline and the Grey Box. Don't like 3rd edition? Stick with 2nd. Like 4th? Go straight there.
Alter the timeline to suit yourself. Maybe the Arcane Age rules never existed, and people could NEVER throw around 10th and 11th level spells. Maybe 3rd Edition was always the way of Toril, with all the new and neat PrCs running around. Or maybe the Spellplague never happens, or if it does it does not change the rules ... or change them much.
You are in control, you and your group. You have all that FR material out there - more published FR material than has ever been out in history, enough material you could literally spend years reading it all (go to Candlekeep and see for yourself, and consider the numerous FR novels.)
You have an INCREDIBLE wealth of material to pick and choose from. A banquet laid out for you and your players. Why not enjoy it?
As for one player wanting this, and another player wanting that, we have all been at those tables. And we all know the meaning of the word Compromise. For that is what we must do, in order to make things work.
Don't give up on FR because it's been changed in 4E.
Consider that a whole new world (maybe desirable, maybe not) has been created, and you can have it, or stick with your own FR. You can have your cake and eat it too. It's your party, and you are in charge.
That's how I see things.
Cheers to my fellow Hobbyists.
