I sometimes see some of the ever problematic game recommendation questions having very specific requirements. And sometimes, I don't see a game I know answering those requirements, but I see how *hacking* a game I know could work.

An example is [this question][1], where Fate hacks or Burning Wheel/Mouse Guard hacks have been mentioned.

This brings several questions:

Would a game hack be an appropriate answer to an game recommendation question? How detailed would it need to be? And finally, is personal experience with *this* hack necessary, or is personal experience with the original system enough?
