Iwata stated that Japanese find western games too difficult or don't care to invest the time in trying to attempt the challenges. He mentions how the Western gamers like a challenge. All this time I was thinking the little helps in the newer games were meant for children, but are probably for the Japanese gamers too. I've been searching where I read that since I did see it on two Nintendo gamer sites but can't find it know. Super Mario Wii U was so easy and I never used Luigi's help.
Since I've got back into Super Mario Sunshine I can see how difficult the game is in certain parts and I can't go forward unless I beat those levels, where as some levels are ridiculously easy. Not giving up through. When Shadow Mario steals my water tank and I have to go through a block course to get to a shine spite it is really hard.
