I RARELY go through games on the hard difficulties. I have to be a big fan of the game in question in order to put myself through that. I'm also more likely to do it if it's a real "hard" level as opposed to a "hard for the sake of being hard and frustrating you." I can understand the feeling of accomplishment, but often I find all the frustration and such to make it not worth it. A game is supposed to be FUN, and if I'm no longer having FUN, why am I subjecting myself to this? That's why it needs to be a really good game to keep me going. The ones that stand out to me are Bioshock, Batman: AA, and Gears of War, with Gears on Insanity being so hard that I actually needed a teammate to beat the final boss, but godDAMN was it satisfying to do so. Gears 2 was frustrating enough on the Hard level, so I'm not going to bother with torturing myself for the sake of some achievement points, especially when I can play other games and have fun with them.
