Original Super Mario bros for NES as well as the Lost Levels. I want to say F-Zero GX cause it is one of my fav games of all time, but i'm used to whatever frustration is expected and I just enjoy it now, plus I'm better at it. That and Age of Empires 2, because although it is immensely fun, sometimes shit just doesn't go down like you thought and then a lot of hard work you put into something just goes down the shitter.
Otherwise, most games that are overly frustrating tend not be my fav games, and my fav games are the ones I play over again
