I'm aware there's a current topic asking people what are the easiest and hardest games they ever played. But my idea is a little different, I want to know which games are hard and why are they so hard for you. Also, with all the answers, maybe try to see if there's a pattern for that (my bet is that most of ther hardest games ever were made in the 80's.
But a few notes: please keep this limited to comercial games. I know "I wanna be the guy" is probably one of the most difficult ever made, but the entire purpose of it is being hard! I wan't to know about games who are hard, but were meant to be played (or at lest bought by someone, thinking they could DARE to play!).
Also, let´s limit it to "default dificulty". Or else everybody will say "Doom on Nightmare level" or something, but then you are playing for the purpose of getting a hard game, and that's not the idea!
