It' not looking for a quick win. It's being able to temporarily use assists or lower difficulty to get past a frustrating no fun obstacle (like a mine cart level) to enjoy more of the game. I gave up on Zelda skyward sword as I didn't want to do the same battle again and again with cut scenes and crap. The rest of the game was awesome, not that boss fight in the pit for the 3rd time.
My point of view is different here. I see games designed around there difficulty. Some games even mention that the best way to play them are on the harder modes. Can you imagine a gamer who plays a game on easy when its meant to be played on hard where the A.I shines and after that gamer beats the game on easy, than comes out and says the game was average because he never played it the way the game was intended.
I finished all the DK games on the SNES, the satisfaction of beating them all was amazing. In fact I finished Battletoads on the NES a long time ago and I felt like the king of gamers because only a couple of my friends could have completed the game at the time. I refinished Battletoads on Rare's Replay and aside from replaying such a legendary game, my satisfaction for completing it with the cheat of rewinding the game dropped immensely, plus just about every other friend of mine was able to finish it as well. The challenge of completely games as an option can ruin the experience for me.
It still comes down to the game. I am playing Ashen atm and I am quite enjoying it. Every achievement I earn and my friends earn feel like we deserve it. Rather than seeing everyone rush and finish the game and obtaining all the achievements because they are playing the game on easy mode. That's just how I feel.
