I play in the hardest settings (when I it isn't out of my reach), but sometimes, it's still not so hard as I would like to. And, believe it or not, sometimes the medium setting are moredifficult than the hard setting. Take Warcraft, for example: in the higher settings, the computer tries to maek strategies, and it's not very good at it, making it less effective, adn thus, easier for you.
God of War is a great game, but most of the combats are easy.
However, I do find the puzzles difficult.
Btw, the next Alone in the Dark game takes the "casual gamer" target to the next level:
It's going to let players skip the hardest parts.
