Rolling Games - Which One Is Your Favorite?

My three favorite roll playing games right now are, king arthur, pendragon, eh, greg stafford and startreck adventures. What really sells me on a roll playing gane is if the game mechanics are designed to create a specific tone or incentivize certain behaviors. D and d five is fun, and i love it. But the one ring is a game that really goes out of its way to put you into the mind set of tolkin's books where hope is as important as combat prowess.
