I saw the title of this thread, and I knew exactly what was coming, as much of this seems to be your perception of the Fantasy Races thread.
In this EXACT PRECISE scenario, the GM is ""right.""
And the opposite of this scenario, where the GM says...
GM "Hey players, what do you want to play in the next campaign?"
Player #1 "A Teenage Mutant Ninja Turtle!"
Player #2 "A Klingon!"
Player #3 "A Krogan!"
Player #4 "A Purple Catfish that can fly and poop fire!"
Pondering for a moment, the GM then laughs.
GM "You players suck! We will play a human only GoT inspired campaign or we will play nothing because I am the GM and I can lord my power over all of...wait...where'd everyone go?!?!?"
...Is exactly what I would expect to happen!
I was never advocating for the GM to be a jerk. I was advocating for the GM's desires to be taken into consideration. Sometimes maybe the players can just do what the GM wants because the GM, as others have said, usually does a heck of a lot more work. Maybe, sometimes, the players should say "Hey GM, what do you want to do with the campaign?" I know if they did that I would have been able to run the frikin Great Pendragon Campaign instead of always settling for something not GPC because I've never convinced a group to play it with me!
Oh well. At least I can convince a group of strangers (or most of them anyway) to play a human only GoT pastiche with me.
I miss my old place of residence only for the group I lost. Other than that, it sucked!
