. . . and this is the sort of DM attitude that they are trying to move away from.
No, the 2024 phb actually backs up what he said about PCs who don't fit the setting & they even showcased a critically relevant page during their own PHB hype.
Rather, they suggest working with the player to accommodate them within the game. - Ask the player what it is about the dragonborn that they like and want to express, and help them find it within your game. You have a better idea of the cultures and peoples than they will.
Is there a culture that has a particular reverence or association with Dragons? Or one with the same independent and honourable streak as the dragonborn. Is there a race with the capability for cantrips that might be expressed as a breath weapon?
Finding out what the player wants, and helping them find a character that they want to play, and that you are willing to allow will work so much better than your current attitude. The attitude of; "I've banned that concept: Try to guess another concept that I haven't banned." doesn't help either of you (unless you specifically derive enjoyment from exercising your authority in this way).
Game settings can be almost infinitely fractal: they have corners and subcultures aplenty where ideas that haven't yet been set in stone might be found. Being possessive about it may lead you to think in terms of a concept contradicting your lore, when in fact it could be used to add more detail instead.
What you describe is backwards in the expectation being drawn out for the GM to accomplish for a player what a player needs to be accomplishing for themselves. The 2014 PHB erroneously gave the impression that a player could roll up to a table with literally anything & expect the GM to somehow make it work but the new PHB even has two separate sidebars about this very sort of divide in character creation in addition to better wording to the character creation section itself.
Sometimes the best solution for everyone is for the player who does not know the cultures & peoples of the world to simply pick one that does exist because the player does not know them & how they differ from their first "can I play..." stab in the dark. I've seen the old way you advocate for play out multiple times in my eberron games and it
never works when a player wants to play an FR race that is dramatically different in eberron (i
e drow & some others) a statement like "
no drow don't live on Khorvaire where the game takes place" or whatever is a perfectly reasonable hurdle for a player to find their own way around during character creation without the GM spending the entire campaign carrying the workload for changing that.
That difference between a player themselves finding adapting what they plan to bring to a table so that it fits the type of game world being run and a GM being expected to find a way or place to make the initial square peg fit is dramatic & long lasting because the square peg will
always be square &
continue to draw on/insert things that simply will never fit. When the GM is expected to "help the player find it within the GM's game" that responsibility will continue to rest on the GM for the length of the campaign even as the square peg continues adding an ever growing pile of square ties.
When the player is expected to adapt & perhaps choose a different direction then that player is responsible for not drawing on square peg expectations without first putting in the work to make the thing they want to draw be drawing on something that actually exists.
@Lanefan I noticed after the post and edited it out since I couldn't remember why it was there while walking the dog in the middle of the night. Your post reminds me
why there was an empty quote box from your
earlier post talking about how the gm is not required to find a way to fit a PC that simply doesn't fit the world. I had considered adding that page from the 2024 character creation.
