From the Reddit:
"I think you're thinking everyone is like you. I think you're likely smart, capable, and able to do a lot of the things that make for a fun roleplaying game.
Most people....aren't. They need that rules support. Sure you and Jason Morningstar (and many other people I know of) could make Savage Worlds into an emo Vampire :TheMasquerade clone, or BattleTech into an RPG about ballet when playing, but not everyone can.
They need the rules, story, choices, to support them and their less creative, dynamic friends, into actually having the roleplaying experience you can pull out of anything."
Ok, maybe most people aren't "smart, capable, and able to do a lot of the things that make for a fun roleplaying game."
Then why would you play with them? When you meet someone like that kick them in the kidney, have lunch, and move on with your life--don't sit down and write a game that enables their boringness. And for god's sake don't write one.
