There are a few games that have been difficult because of game mechanics more than anything (the frustrating kind that puts you off the game) but here are some that I enjoy the difficulty of:
- Viewtiful Joe: Difficult as hell, but every time you mess up you know it's your fault. - Jak II: I played this as a kid and ended up abandoning it for about 6 months because I got stuck on one mission. - Timesplitters 2: Trying to complete this on Hard mode is insanely frustrating. The levels are short, but you only get one mid-level checkpoint per level and one mess up can end you. - Super Meat Boy: For obvious reasons. - Rayman Origins: The very last area (Land of the Livid Dead) is ridiculous.
I was stuck in a part of the castle because an earthquake blocked my way out to the hallway. Found a way after jumping outside the window and was lead into a new room. Found a hole in the wall and ended up in a a small library. Pulled out some book and it opened a new door for me. Picked up a key and the monster kicks in a locked door right in front of me. Luckily he didn't walk inside and that's where I stopped playing.
