@gameragodzilla Thief did this brilliantly just by making death the only game over.  That's all you had to do.  Then, if you got caught, well, you either fought everyone if you were really good, or ran and hid, and there you go.

Really, it comes off to me like they wanted to be able to shit on you if you fought, for being a bad guy or whatever, and I really hate it when games try to herd you into making bad choices and then call you shit for it.  KOTFE was really bad for that.
