3e was the era of Eberron and the Adventure League used Living Greyhawk. The official setting of 4e was Nentir Vale and only 2 published adventures took place in FR.
The OP should have been worded differently if the author wanted a different result
I had no desired outcome when I started this thread other than conversation.
Nor, am I surprised that Enworld's Grognards voted overwhelmingly for Gary,
(I would have been surprised if the opposite had happened, frankly).
Eberron may have been introduced in 3e, but the setting was introduced later in the development cycle.
Eberron is a much, much better fit for 5e.
3e was thirsty for feats, and the Dragonmarked feats, often required an investment of 2 or more feat selections. 5e bypasses this, by developing interesting "race" alternatives.
5e also puts a greater emphasis on roleplaying, and less emphasis on constantly increasing "your numbers".
Adventure League, RPGA Network, Tournament Games....most players, even hardcore players, don't play in 'official' organized play.
My innate response to cries of "What about A.L.?"
is similar to my response when people exclaimed "What about the children?"
in the period of the late 80's/Early 90's.....typically I want to mock them.
My alignment is Neutral Good,(with naughty word tendencies)
