Before the introduction of game achievement system such as the Xbox 360, i normally just play on default setting, most probably will not touch the game again after the first playthrough. Now... i study the achievement list even before i unseal the game, try to beat the game on the hardest difficulty during first playthrough (some games) just for the sake of unlocking the game achievements... Gaming has never been so frustrating before, but watching the unlocked achievements pop up on screen is sweet... damn...
