Legend
I once ran an all dwarf campaign for Savage Worlds. The premise was that the Grimké Sisters, the most eligible bachelorettes in the city, needed husbands and invited all the eligible bachelors to participate in a quest to win their hands. My only requirement was that each PC was to be a dwarf who was either interested in winning the hand of one of the stout Grimké sisters or helping someone else win one of their hands. A marriage to one of the Grimké sisters would bring wealth and prestige not just to an individual but to their entire family as well so even if your character doesn't want to marry he or she has incentive to help a family member achieve matrimony.To jump from seeing the DM say "Hey, I'd like to set up an all-tiefling game, please create a tiefling" to the idea that the DM has the entire campaign already scripted out in their head and you're there to just be a puppet... is such a ridiculous jump to me that I can tell just from that statement we shouldn't ever be playing together.
Besides making a dwarf, the only other restriction was that I limited their option for "supernatural" characters. Wizards and alchemist were fine but they couldn't make a superhero for example. And the reason I had them all make a dwarf was because I wanted to explore themes of tradition, sexism, exploration, cultural exchange, and change. Having them all be dwarves made this easier.
The twist to the campaign was that the Grimké sisters weren't really looking to get married. Their plan was to get all the men of marriageable age out of the city making it easier for the women to seize the government buildings in a bid for political parity.
