D&D is probably one of the whitest hobbies.
It's based on Tolkien, a white man who wanted to make a mythology for England, for the white people of England. Gary Gygax (a white man) adapted that lore into the Chainmail wargame and D&D was born.
And you know black people aren't going to play it because it requires reading at least half of 1 book, which is a bridge too far for most YN's.
