I generally just like playing videogames to entertain myself for 20-30 minutes, and put it on normal. I rarely re-play a game, unless I love it, like Metal Gear Solid 4 I must have played on every level... but it had a lot of replay value to me because of the different awards and such from playing a session a certain way or strategy. Unless you're just amazing, you couldn't play MGS4 on Boss Hard the first time around, because you'd die before you learned the controls.
