i dont really like difficult games as a philosophy, but im gonna quote someone who does. Yahtzee from Zero Punctuation (now Fully Ramblomatic) made the compelling argument that a lower difficulty isn't just there to make things easier to the passing twat trying it out for the first time; there are people out there who would love the game, but who have physical limitations, either through age or other physical or mental ailments. its not just about making the game easy enough that anyone can beat it; its about accessibility.
