I can get unified in the sense that all parts can be used with all other parts but monolithic does nothing, they need some more experimental voice on the team to counter them
mystara could be done with the right team, also the dog folk could sell the product of the furries alone.
but I can see darksun might have some taste issues but stranger setting with psionics as a class like eberron with artificers could do well
rationally speaking a secondary dm focused book only about how to build up settings and adventures would both sell reasonably, be useful for retention of customers and even if less money is made would be so useful that it being a loss leader would be viable
I have finally finished this book, I found the ending to be dry and the latter half feeling rushed.
regardless I can finally kick this off the bucket list as the book where my name comes from.
it is a bit of both, it is selling people on the idea of playing this option from having it at the table to it being part of a supplement for sale it is a factor, and thus making something desirable is kind of core to all sides of the hobby.
it is a question of how do you remove the human without making them too monstrous to fill their role, elves are to be a fantasy, dwarves are endurance, orcs are brutality and so on.
I can see that problem orcs need to be something other than humans with different dental work
how is a dragonborn a half-elf, a Dragonborn is not even half dragon, goliaths are a small type of giant so not half anything just short by giant standards
my problem is the versatility of elf more than anything, it being a positive other tends to get many things in the same area, plus lots of old nerd writers read lord of the rings and it tends to influence things
