I find it ironic that Andrews McMeel decided to breach contract with a Black writer, right at the beginning of Black History Month, while promoting an RPG by a White writer on their front page called #Blackbirds (which BTW is well worth checking out).
Folks in this industry always seem surprised to discover that even the most successful RPGs are but blips in comparison to the other titles typical book publishers put out. D&D and Pathfinder are the only two exceptions, each for very different reasons. And we'll be experiencing the D20 glut 2.0 very shortly as every 3rd party publisher and their dog puts out their own D&D fantasy heartbreaker. And you can bet folks will be making their decisions based on the politics of the publisher rather than the quality of the game, and shaming the folks who play the wrong one.
