Games that have difficultly setting play out like this for me:
First playthough: Normal mode, to get used to the game and play though having bit a difficulty hear and there but not so much to keep me from moving on.
2nd playthough: Hard mode, now playing just for the difficulty I know the story now so can skips cutscenes I've seen. I want to find different ways to beat the now suped-up bosses, explore all the quests, or/and choose different routes if it's nonlinear game.
Any playthough afterwards: Easy mode, half of the games I own I really love because of the story and on rainy days I replay them for old time sake. These times I'm not looking for that much of a fight, I play casually and is able to remember some of the best bits of the story, with maybe the occasionally difficultly bump up during interesting boss fights.
So yah, I love having an easy mode, plus of course with whole making it easier for new people to get into gaming thing.
