Fable: The Journey. In an interview with OXM, Peter Molyneux explained the player's bag of tricks would be limited strictly to magic. He added, "We could have done melee weapons, but the one thing I hate about melee weapons, and guns as well, is that the human brain is encoded to expect recoil from those things."
Molyneux said that satisfying that expectation of physical feedback was necessary, and that "visuals and the sound isn't enough." It's that weakness that makes the game's robust magic system work. Molyneux explained, "The thing about magic is there's nothing encoded in your mind about how it should feel." That's true! The only preconception we have in mind about magic is that it probably requires a lot of gesticulation; something we know for a fact the Kinect excels at.
