Hard : because i (think) am a
fucking hotshot 
Unless with some games, where the (ultra) hard mode is used (ironically) to defeat the purpose of a
challenge, and makes it absurdly difficult (enemies who hit with 100% accuracy, for example). Fortunately there isn't too much of that. Although most of the time you'll find that it's a relative thing, in which your own abilities/skills and risk taking will readily adapt to the given difficulty you've chosen.
Although t's only a
game afterall
