There are as many different types of players as there are different types of games, and that's a good thing. If someone doesn't like the way one game plays out, or if it's too easy or too hard for them, there are literally thousands of other games out there to choose from. What's too difficult for one person will be the perfect challenge for another and too easy for yet another. It's just how it is. :) At least in the case of the 3d Mario game they are giving the player an option to continue if it's too hard. They don't HAVE to use it, it's their choice. If the option weren't available perhaps some people would give up and go play another of those thousands of available games mentioned above. In my opinion it's better for the game designer to at least offer some kind of "out" for people who simply don't have the skill to get through the difficult levels. It's a form of player retention. :)
